<VV> Front Wheel Camber

While the shims would act the same for the late model, no one uses them 
as there are eccentric adjusters on the lower control arms on lates!

An alignment guy who has worked on GM products for years would know what 
size shim to start with, but I'm not that guy....

IIRC, there are two shimable bolts on the upper control arm, you change 
both shim packs to vary camber, and one shim pack to vary caster. One 
shim pack change would rotate the upper ball joint front or rear 
relative to the lower ball joint, so that is caster, or SIA kind of.

This shim setup is common to many GM cars and trucks, even through my 96 
full sized Buick Roadmaster Wagon.

Start with two 1/16" shim changes and see what happens.

In other words, adding or removing what thickness of shim will change the camber 1/2 degree?  It seems to me that there should be some base of knowledge on this and that it should be the same for a late model.
