#1 What is the thread pitch of the little screw that holds the condenser to the side of an 009? My Square had been converted to an 009 with electronics inside. They gave up last night, so I put points back in. That screw was not there and I need a replacement.
#2 Where do I get the upper bump-stop bushings for the rear? I have added pictures. These are worn out and rattle as I go across bumps. I want to get them replaced.
You can see how far over the top moves because the bushing is shot.
#3 Why does getting old make you forget something that was fresh on your mind?

| As far as the bushing goes, I would try ISP West, they are the go to for most things Type 3 related. If they don't have them they can probably point you in the right direction, super helpful nice guys! There is a guy on here out of Washington Boo-Koo-Z that usually has tons of parts listed, you might try contacting them directly If you dont see what you need posted on the Samba. Hope this helps! |

Yup, Z bar, and it's missing multiple pieces of rubber parts for it. I believe ISP has the parts to rebuild them. Quite a few people just remove the Z bar set up altogether, as parts to fix it are expensive.

What is it? Anti sway bar of sorts?
What are the drawbacks if removed? The noise is miserable.

Took the rattly arms off today and got rid of the metallic clunk when driving over bumps. It also cured an annoying squeak that I have been chasing since I purchased the car. Two for one.
Driving impressions are zero difference before and after. I was even driving through some bumpy country roads with decent turns at decent speeds. No noticeable difference. Thanks for the tips, guys.

Don't remove it....fix it. It has a use. You just can't see it from the drivers seat...and have to either have some load in the car or get into the right driving situations for its usefulness to be exploited.
Go to the Shoptalkforums and search for a thread called "The Z bar illustrated".
The Z bar is a camber compensator for swing axles...and fairly well designed. Ray |

Not really, at least in the stock form. It was an overload spring that only worked if BOTH sides were under compression. It accompanied VWs softening of the main rear torsion bars. The idea was to let the rear lean more when cornering, in order to reduce oversteer by making the front suspension take more of the cornering loads.
However, if that was all they did, the softer bars would have let the car bottom out sooner when driving straight and hitting RR crossings or boulevard intersection drainage humps. So they added this overload spring to keep that from happening, while allowing the softer rear main springs.
'67 and up swing axle Bugs used a similar overload spring, for the same reason.
Some have found that if these links were tightened up (shimmed), the spring behaved a little differently, contributing to some roll stiffening. This sort of defeats the purpose, though.
Check the threads on "rear Z-bar" or similar, and decide for yourself. You can search the performance and also the Bug forums for threads.

Yes....good point.....not in Stock "USAGE". The form is fine. Its been used with good success on several cars.
The problem is......as you noted......that VW softened the stiffness of the rear torsion bar as you noted....when they added the Z bar......which is counter productive.
This is not a ride comfort device. It's designed to lessen camber as the body rolls. Stiffen it up a bit with shims and bushings and pair it with good shocks and it can work as designed. Ray |
