I forgot to mention we put new bushings in the four front stub mounting locations before any sheet metal was put on.

Front fender alignment to the doors was not difficult, so I'm leery of frame problems. The question remains--why only is the right side tire rubbing?

The alignment shop was emphatic that "these cars" have problems with drooping of the subframe itself in the arced area where the front suspension is located. He said he could bend this area to correct the problem. But, as I said in the OP, how can this be done without affecting body panel alignment.
