Upper Control Arms

This has probably been asked before but here we go. Upper control arms from a 75 Dart Sport with drum brakes. Would they be the ones with the big ball joint? I have 70 Dart which I want to convert to disk brakes/big bolt pattern. Would the spindles, caliper brackets and dust sheilds from an Aspen (F-body I think they are) work with the correct upper control arms and correct lower ball joint ?
