Lower control arm needed?

Yes, of course rebuilt parts shouldn't need replacing. It only makes sense (to purchase the adapter shims) if you'd already installed new upper bushes and (A-body) ball-joint.
I know for a fact, though, that a 1974 Duster, Challenger and Satellite all have same upper bushes, 'cam' bolt kit and upper b-joint.
I do think, however, that the stamped-steel part of the UCA may be different between the A and the B/E bodies. A complete 'unit' is sold thru RockAuto for $177. (CDN). but I only see a listing for the E-body and not the A.
Can someone confirm either way?

The cam bolts, bushings, and ball joints for the 73+ A-body UCAs are the same as B/E body UCA's (as well as others), that's correct.

But that's about the only thing they have in common. The dimensions are totally different.
