UCA Problem!

Those "washers" on the ends of those upper control arms just aren't right for stock, factory, rubber replacement, bushings.
I think those washers are needed for "POLY" bushings, but i haven't had to replace bushings with poly ones, in probably 20 years, so my old memory is probably shot to hell.
I think those washers were put in your box of parts in error.
If you are replacing bushings with a quality, well known national part, Moog, NAPA, Car Quest, something of that nature, you should be good to go right out of the box.
These bushings in the pictured UCA's were recently done, with MOOG parts, and no extra washers are needed.
Good luck.
