Oh STOP!

I ain't always right, but I'll throw out every idea I come up with.....one of them has to be close!   Just glad to help when/if I can.....same as everyone else here.

Just to clarify the reason for the holy shims, and the cotter pins that go thru them. When the rear suspension moves up/down, the t-arm shims are held tight to the arm, and want to move with it. Once they move upward, out of the "pocket" in the frame where the end of the shim with the hole sits, there's nothing to keep them in. The more movement on them, the farther out of the slot for the bolt they come. Eventually, they simply fall out. Originally, there were NO holes or cotter pin in the t-arm shims. Shims were falling out left and right. Once GM figured this out, they came up with the holes in the shims, and holes in the frame to insert the cotter pins, to hold the shims both down, and to keep them from falling out, even if the bolt gets loose, or the bushings fail. Most Corvette alignment places have the holy shims in stock, but rarely have the un-holy shims....which are needed if doing a full-on resto on the older cars. Sometimes they get mixed up, or the alignment guy just ain't paying attention.....or he just flat out forgets to reinstall the friggin cotter pins, which is apparently what happened here.
