Check that right rear tire - you are looking for a 'lump' or uneven edge wear (get the car up in the air, spin the tire while watching the tread - any deviation from true is the lump). It will be subtle, and caused by the positive camber wear. That is most likely the wobble component of your ride issue. Swap it out with a good full size wheel/tire assembly (maybe from your '84) and take it for a test ride. Get the camber issue corrected before going much further (replace the bent part). If you can see the difference in camber due to the bend, its enough to wreck a tire, and change the other angles significantly. Also check your ride height. You are looking for side to side differences. If present, address that also. That affects/limits the range of adjustment available while performing an alignment.
