14 inch AM Racing wheels with 3.75 inch backspacing.
That's why I replaced the large wheels and tires the previous owner had on her.
I wanted the wheels back in the wheelwells.
so you're minus a half inch from factory back space, and plus 5/16 from the 73+ brakes so there's 3/4
of an inch out further and you've got a taller tire. add the soft factory t-bars and some clapped out shocks and anything below factory ride height you'd for sure be into the fender (which you've already discovered).
