Bought some 6' shims from 4-wheel parts last week. They showed up a few days ago and I installed them yesterday. 1st off, the hole in the shim was way too small. I had to drill them out to 9/16. After that, I installed them and when tightening up the U-bolts, This Happened! /forums/images/graemlins/angryfire.gif Who would make degree shims out of cast aluminum?!? I think some degree shims from A-Tron are in order..... Thanks for listening to my flame. I think I'll take these pieces-of-junk back down to 4-wheel parts and tell them what I think! Thomas.
