Upper Control Arm Shims
« on: November 29, 2020, 09:05:23 AM »
My 66 Shelby had about 10 alignment shims per side used with the upper control arms. Did 66 Shelbys use more shims since they had the longer pitman and idler arms?

The shims used on the upper control arms are for adjusting caster/camber to achieve the proper wheel alignment. The shims have nothing to do with the steering linkage components.

You can always use a thicker shims to lower the shim count.

It's either in the shop manual or assembly manuals where a starting point thickness is provided with the shim sizes.

Note that the original shims are squared across the top.  Lots of incorrect round or ones with a tab.  Originals can usually be cleaned and zinc plated.

Your car does not have the Shelby A arm drop correct?

Correct. My A arms are not lowered.
