Need help with UCA bushings

When I bolted up the UCAs, it seemed like they were ridiculously loose. I had had the Moog offset bushings installed, and the inner shell of these bushings seemed like a very loose fit on the cam bolts. With the nuts finger-tight there was almost an 1/8th inch of slop. What's with that? I thought it might have something to do with these washers that were left in the parts boxes -- four for each side, two big and two little. The holes in these washers are a snug fit on the cam bolts -- the problem is you can't fit even one washer between the flanges on the inner fender. The washers have a sort of raised lip around the inner hole that makes them too thick. They look as if the raised lip should socket inside the end of the bushing shell, but it doesn't fit. Neither does it fit in into the slotted hole in the frame. The instructions explained how to set the offset, but didn't mention these washers at all.
