Mark, SNIP I can't tell left from right. I know that the upper arm has a extra collar on the rear bushing. SNIP The control arms them selves are interchangeable from left to right and from all AMC products except Pacer and Eagle from 1970 through end of production. Just install the ones with the bushings, to the rear.
