upper control arm rear bushing

I used the MOOG offset bushings. They came with 4 washers per side (2 big ones, 2 smaller ones). The washers had about 1/4" of 'shaft' to one side. The 'shaft' was just a touch to big to fit inside the bushing. I touched them to the grinder to slightly bevel the edge of the 'shaft' so it would start into the bushing. Then I stuck them in the vise and pressed them into the bushing. Hope this helps.
