jberger - no, I got rid of that one. That was the one that made me think I needed to JB Weld though. Not necessary with this new washer.

It worked!
It took a few iterations to get the spacers the right dimensions but it worked. It took 2 spacers and was right on the money - .004"!
A few pics:
Thanks for the help everyone!

That's an interesting way of doing things. Hopefully the paper doesn't interfere with the rubber o-ring or decompose under use.
By the way, it's not always necessary to use three shims to reach your goal of .003-.006 end play. Use two or four if that's what it takes. The motor wont know the difference.

Check the runout on the flywheel now. I know early bugs used a "paper" gasket.. but I just don't like the looks of that. Something else is amiss here.

Well, the three shims is a much talked about procedure.
While some say four is OK virtually no one accepts two as a viable option.
Think of a roller bearing, outer race, inner race and center roller race.
The center of the three shims is in essence the rollers. It gets lubricated and they all spin, or not, at varying speeds.
Two shims simply takes the bearing comparison out and introduces the possibility of wear, over heating and siezure becoming very real.
No matter, Err on the side of caution..... use three shims.

| I would think that two would be fine with an automatic tranny. Really don't know for a manual with the pressure from the clutch being taken up by the shims. That said, an awfully lot of engines just have a thrust bearing sized to fit against the crank so the bearing to crank interface sees the full speed differential. |

All Porsche 356's and 912's use one shim. Same design except they get revved to 6500 rpm.
Ideally I would use a three shim stack, but what really matters is where it's set. I've used two and I've used four in air cooled motors.

I think this thread is done, right?
Cuddling, listening ,and not falling asleep works for me

Eh I went with three. My issue is I didn't have the right shims regardless. I would've needed 2 of the the hard to find .24mm shims. I did check the runout with and w/o the paper gasket. Pretty much unchanged.
