I got the new ubolts yesterday so about to put the back in together. The left rear shim looks original; it appears to have been attached to the leafs when they were made. Also, the saddle that the leafs sit on are different; the right has the hole for the pin on the bottom of the leaf to drop into for alignment, but the left has a small bump that fit into the matching hole in the bottom of the shim. I had to drill out the shim to 1/2 inch so it would fit onto the bottom pin of the new leaf (the shim now has a 1/2 inch hole all the way through). I’ll tryto take some pictures before I go together with this.
