Thanks for these additional observations. Even if I don't respond quickly, know that I'm processing these comments and checking things as suggested.

Interestingly enough, I have a similar problem. Looking forward to your resolution.

I'm just brainstorming some things that I would check if I was in that predicament...if you have a 24" level (or other rigid, trusty straightedge), you can place it across the bellhousing flange and just eyeball if it seems parallel with the firewall. Of course, the puffy nature of the tarboard might obscure the view of a lateral line on the firewall.


I don't know if this photo is very helpful. Due to the camera angle, irregularities of the tar board and that it obscures the body above the transmission, it's hard to tell if it shows anything definitive.

The other thing I'd be tempted to do is drop a plumb bob from a centerpoint on the body and let the bob hang in front of the tranny input shaft, that might show you if/how much it's skewed. For a hanging point on the body, you might use the bracket that is for latching the decklid spring into.


Well, this shows the end of the input shaft in alignment with the center point of the body (the spring bracket hook for the decklid), but the forward part of the shaft appears to be angled to the left. I know it could be the camera angle, but I did my best to take this photo head on.

Is the marking in the center of the transmission carrier in line with the center of the lower rib of the transmission?
If not, the gearbox and engine will be off center.


Again, I did my best to take this photo head on. I know a camera lens can create some distortion the closer you are to the object, but I don't think that is a factor here. Looks like the center rib is slightly to the right side of the car relative to the center mark on the carrier and that the rib trails toward the left side of the car as you move forward.

how does the hockey stick shaft look under the back seat? Is it in the center of the hole? Does it seem to be coming in at an angle? Not sure if you can tell much by looking there, but maybe?


The shift rod angles to the left side since the the shifter is on that side of the tunnel, so normal, right? How does the rest look (other than crusty)?

Let me know what you think based on these photos. I think the transmission is angled slightly to the right side of the car, but I'm not sure what approach will correct or at least improve this situation.

I know this is of no comfort to you - especially since you're sure that it was squared up before this recent engine work - but to me it still seems like whatever's going on is happening at the fore end of the transaxle Think

Good job with the plumb bob hookup, but I would use some much thinner, more pliable string rather than "rope," it would be more precise. But what you've done seems to serve the intent here.

I just lifted the seat in my '66 convertible and snapped this pic (the shift rod is out at the moment). It seems like my shift lever is pointing pretty much dead straight, even given the shifter stick offset up front (I think the slight shifter offset to the left has a scant effect at the back end, what with traveling 4' from end to end (the length of the shift shaft). Maybe you can trig that out Smile In other words, I don't think they'd skew the trans mounting to accommodate a minor offset of the shifter 4 feet away.

I have to agree that I need to focus on the forward end of the transmission. I gave this another look this morning and took photos. There is a crack in the rubber mount, but I don't think that would cause the misalignment. Comparing my shift coupler photo to yours, I see that the rod entering from the nosecone on mine is definitely angled. So it seems like the forward end of the transmission needs to shift to the right side of the car. So if I go ahead and replace the front mount, will I have the wiggle room necessary to shift it to the right? The photos I've seen don't show slotted mounting holes. Maybe shimming up the right side stud would straighten it out??

See any clues in these photos?

I would definitely replace the nose mount, you've got nothing to lose, and as aged as yours looks, I would think that the rubber is stiffened, a new one could provide you with a better motoring experience. However, there is literally zero adjustability in the nose mount, and it only goes one way up, with the open/flat sheet metal stud plate oriented up ^

And yes, comparing your nose cone to the chassis sheet metal (albeit slightly molested), it's clearly offset and angled to the left side of the car.

Are you absolutely 1000% certain this condition was not present before the recent work? Do you have any pics you could reference?

Oh, to change the nose mount with most your stuff hooked up:

- Remove bolts holding rear mounts to cradle
- Disconnect shift rod coupling
- Actuate throwout lever by hand and place 3/4" wooden block in front of T/O bearing fork
- Thread ratchet strap around trans (at lower mounts) and wrap around rear apron (or all the way out and around rear bumper)
- Slowly ratchet trans rearward just enough to slide old nose mount out and new one in

You'll feel the tension build on the ratchet strap because the axles will begin to pitch forward and slightly flex the spring plates outward, the bowden tube may also add some stiffness. But the brake lines won't become taut and the block under the throwout fork will provide enough slack in the clutch cable (you might skip the wood block, the throwout spring will just add a bit of tension to the ratchet pull, I wouldn't want your clutch cable to drop off the hook up front at the pedal).

This is how you can do it solo, or get a (really) strong buddy over to pull the works backwards while you swap mounts.

Unfortunately I don't have any photos for reference, just my recollection of it being centered enough so as not to be noticeable.

If the nosecone is angled to the left side of the car, then I would have the opposite alignment problem (engine shifted to the left instead of to the right as it is now), right?. Confused

Thanks for these tips! I was just working on my one-man-operation game plan for this task. I did some pedal cluster upgrades while waiting for the engine, so don't need to worry about the clutch cable slipping off. Very Happy Using the ratchet straps to draw the transmission rearward is genius! I'm fortunate enough to still have a VW parts store a few miles away, so I should be able to get on this. What about my thought of adding a few washers behind the right side of the mount to shim it up and maaaaybe shift the alignment more toward center? I'm not going for perfection here, just want to get enough of a gap between the tin and body to get that bus seal in.

I think the opposite is true. If the nose cone is pointing left, then the engine would be crowding against the right side of the engine compartment, because the fulcrum is the rear transmission mounts/bracket.

So, you probably need to scoot the rear of the transmission to the left somehow. That would straighten the nose cone and move the engine away from the right side of the engine compartment. I'm not sure where the "give" will come from to do that, but maybe you could enlarge the holes in the main bracket that bolts to the frame horns.

It still doesn't make sense that the gap appears to be even on the left side of the engine compartment, but maybe it's an optical illusion.

You thought about shimming with washers? Shimming where, under the front mount? I wouldn't do that, you could throw things off and worsen things, possibly elsewhere. I'd first replace the front mount and see where you're at. Other than a little play in mounts and brackets, this is a relatively fixed triangle you're dealing with. The whole situation is very curious, it doesn't make sense that it could go so wonky without notice. Did you have the OE type engine seals in before? Those could've masked something. And did you change the muffler? That could account for a more noticeable asymmetry in the tail pipes.

The nose cone area is a fixed point, and other than some CW/CCW rotation of the bell housing, the rear arrangement is relatively fixed, it can go fore/aft a bit, and "rotate" a bit (towards 11 o'clock or 1 o'clock), but there's no real way to skew left or right using the nose cone as a pivot point while keeping the transaxle in a level plane, does that make sense? It wasn't designed to do that, but that sounds like what you're aiming to do.

That's why I keep asking what it was like previously, I'm wondering if something was bent previously. There was another user recently who had "clocking" issues, his motor sat sideways, so that was something that could be remedied by rotating the bell housing CW or CCW to level out the motor. You seem to be skewed in the lateral axis, which is weird.

I took some liberties with your pic to highlight some peculiarities...

Image may have been reduced in size. Click image to view fullscreen.


For one, I have to wonder why somebody went ape-sh*t with the sheet metal around your shift coupler. The solid yellow lines literally follow the sheet metal edges that form the opening. In the upper-right (left rear of car) the metal is literally torn and separated, and almost looks like some metal is either missing or bent away out of view.

The centerline is, well, the centerline of your shifting apparatus, going straight into the nose cone.

Now, I know we're likely dealing with some parallax with the photo optics and whatnot, but the whole works looks very much shifted to the right in this photo (left side of car). It just doesn't look correct.

Can you observe the actual condition straight overhead and confirm whether this is the case? If it's truly offset like the image suggests, I would be looking at a lot of different things and measuring and comparing a bunch of different points.

If you are going to have to shim with washers, cut the washers with a gap to allow to add/subtract without having to disassemble the whole thing.

I misinterpreted what you meant by angled to the left. I thought you were referring to the nosecone being shifted to the left.

I checked the position of the forks relative to the brake backing plates. The best I can tell, each fork is the same distance from its corresponding backing plate. The old engine seals were pretty much gone. There was a gap between the tin and body all the way around. Not necessarily perfectly uniform, but more uniform than what you see in the photos in my original post. I thought if I shimmed between the right side of front mount and the body it would nudge the right side of the transmission to the rear. I could then put a shim/washer between the cradle and the fork on the right side to help the holes in the cradle and right rear mount line up. The slotted holes in the left mount might give me enough wiggle room to get the bolts through. The pivot point would be the left stud on the front mount. A couple of washers might create enough deflection by the time you get to the right rear mount. I don't think this would change the vertical position of any part of the transmission. Something related to this problem is not as it was when this bug left Wolfsburg 61 years ago ... and it's not necessarily a surprise. That's a long time and a lot of miles ago. I'm just thinking a weird situation may call for a weird solution. That said, I appreciate any cautions any of you want to share ... the last thing I want to do is create two new problems trying to solve this one.

The shim trick may work, it's worth a try, if for no other reason just to see what the result is. I'd just pay attention to the response of the shift coupler, make sure it remains all smooth and copacetic Wink

You mention the left side stud of the nose mount being the pivot point: what I envision is, the back of the trans indeed wants to go leftward, but then where? Up, that's where, because the cradle is an arc, an upward arc, I can't see it going left without going up too. Edit: as I keep mulling this in my mind, I suppose if you could swing the entire nose cone to the right, it would kick the engine left and provide your desired outcome, I would just be surprised if some shims on the front mount accomplish that....I hope I'm wrong Smile

I like my59's idea for slotting the washers, just like real alignment shims Idea

Thanks for marking these peculiarities. Feel free to do so on any photos I post if it helps ... which it certainly did here.

As for the sheetmetal butchery ... who knows. My best guess is that someone got fed up trying to get an 8mm wrench in there to remove/tighten the rear set screw and started to enlarge the opening for more working room.

I think the shift rod in the lower part of the photo is headed to the left side of the tunnel because the shifter is on that side of the tunnel, but the rod entering the nosecone does look angled consistent with the angle we saw on the input shaft behind the plumb line. It's certainly possible (likely) that measuring and comparing a variety of fixed points will reveal imperfections that are contributing to this problem, unfortunately they are probably imperfections that cannot be easily corrected, so compensating for whatever flaws exist is probably the most reasonable option.

The shim trick may work, it's worth a try, if for no other reason just to see what the result is. I'd just pay attention to the response of the shift coupler, make sure it remains all smooth and copacetic Wink

You mention the left side stud of the nose mount being the pivot point: what I envision is, the back of the trans indeed wants to go leftward, but then where? Up, that's where, because the cradle is an arc, an upward arc, I can't see it going left without going up too. Edit: as I keep mulling this in my mind, I suppose if you could swing the entire nose cone to the right, it would kick the engine left and provide your desired outcome, I would just be surprised if some shims on the front mount accomplish that....I hope I'm wrong Smile

I like my59's idea for slotting the washers, just like real alignment shims Idea


I agree, the left trans mount would start climbing up the cradle, but I don't need much movement at the cradle to translate into enough in the engine bay, so maybe a 1/4" there will do the trick without throwing the rest of the geometry unacceptably out of whack. As they say, there's nothing to it but to do it ... and see what happens. If the shims don't work, I'll pull them out and work on a Plan B.

Slotting the washers had crossed my mind, but thanks to my59's for mentioning it. A very good idea! I think I'll just run over to Harbor Freight and pick up their box of assorted body shims ... I've got a feeling they'll come in handy for whatever else this bug has in store for me. Wink

If you are going to have to shim with washers, cut the washers with a gap to allow to add/subtract without having to disassemble the whole thing.


One of the best suggestions EVER !!!!

Did you losen the nose cone mount and remove the coupler when you installed the new cradle mounts? If not, maybe things got shifted around and possibly bent during install. You did mention that installing the mounts was a PITA.

No I did not ... good point. I'd think that front mount would anchor that point pretty well though. I attributed the usual fitment struggle to the questionable quality of aftermarket parts. I'm picking up a new front mount and shims this afternoon, so I guess we'll see how this experiment turns out.

No work on this project today. Autumn colors have finally come to the local mountains, so it's time to take my wife on a scenic drive up to Julian. Very Happy Back at it tomorrow with an update and photos ...
