I pulled the bent front suspension crossmember off my wagon and found a rather thick shim under the front bolt between the crossmember and the body.

Is this someone's cockup, or a legit part?

Seems it's only purpose would be to adjust the anti-dive angle of the lower control arm?

If legit is there a spec for this shimming?

The shims are legit. Mine has them too. When I took our 122 to Line Up shop in SE Portland, I handed them a ziplock baggie full of shims and they used a few of them to get the alignment correct.

If you need replacement shims, you can always get them at Parkrose Hardware. I took all my old shims, stripped them down and had them re-plated.

I have pulled two 122's apart and never seen shims there. Common at the top A arms for alignment purposes, but not cross member to frame.

Yep... mine had a couple.

This is the right way to adjust caster in these cars. To wit: http://www.vclassics.com/archive/align.htm

Did you use any of those settings on Blackie?

Not sure... I let the Line Up Shop figure that one out. I just told them I wanted a slight bit of camber for handling, but wanted it streetable and to save tires.

Castor is a good thing[tm].

Put as much in as your arms can handle. :mrgreen:

+ Castor improves self centering
+ Castor jacks weight in turns
+ Castor cambers the tires when turned
- Castor increases effort to turn the steering wheel
