Upper Control Arms

Just note; A lot of those "Who To's" may state the safe answer, not the whole answer.

I would check before investing in another set of control arms. Every part outfit that has ball joints for old mopars only lists one size for 73-76 A-bodies with no differentiation for brake size/type and it's the bigger one that is alos used on B/E bodies. They will all list a different part number for 72 and older.
