'65 Dart rear end & wheelwell Q's??

My '65 Valiant is running the stock 7.25 rear for now, but the spring perches and track width are the same for all a-bodies.

I was able to fit a 245/60/15 BFG Radial TA under my wheel well. It's mounted on a set of custom Wheel Vintiques steelies that are 15" x 8" with a 4.875" backspace. Tires rubbed at first but I put new springs in and had them arched 2" over stock for extra clearance. Problem solved.
