Negative camber

Backwards. Negative camber is when the top of the tire is tipped in toward the frame, not out.

B/C/E body UCA's will not physically mount on an A-body, the mounting ears are a different width.

To the OP, pictures of the issue would be very helpful.
Yes think frame pushed in a little..but all drives strait as an arrow. But I know tire going to wear on inside as much as top of tire is inward. Don't want to try and stretch frame as 50 years old it could do more damage then good. Just thought maybe tubular control armis longer and could offset the negative
