A body non 7.25 rear end

The F is wider, but not by a lot. 9/16" of an inch or so per side.

Our car is an early A ('66 Cuda) and it's running 235/65/15's on "7 wheels.
I doubt it has an extra 9/16's per side as the tires rubbed all the high spots off the undercoating on the outside of both wheel tubs as it is.
