offset upper control arm bushing placement

I dont think so.Those washers go with the previous bushings. The offsets have their own washers. At least the MOOGS do, or used to.All Im saying is dont double washer.I doubt you could even if you tried; theres just not enough room.On the other hand,if your bushings Dont have the washers,then,yes.One washer each end, each bushing.
