Just curious of the frequency and size shims you may have found, that was factory assembled for your cab mounts. My front mounts had a 3/16" shim each. No shims on the rear.

I'm rebuilding a truck and just guessing here, but seems I'll need those or similar. That or it was a GM miss.

Here's a page (86) out of the assembly manual. The shim(s) is #9.

Thank you.
