Widest wheel and tire fitment on A-body

[DustedUBad]

Hey guys, I have a 72 duster, what is the widest tire you can fit under it, I would like to run some mickey Thompson E/T drag radials on it and some wider pro stars with less backspacing, I plan on relocating the leaf springs, and mini tubing it taking it back to the frame, and would like to keep from trimming the quarter panel lip if possible. The car has L60 M/T sportsmans on it now, but the offset is too wide and I have to run air shocks to keep the car from scrubbing the lip. 295s don't look as wide as what I have now. Any help would be appreciated.

I run Mickey Thompson 325 on my 74 Duster it has been mini tubbed

I ran some 28 x 13.5" wide bias MT Street ETs on my 72 Duster with a mini tub. It was close, if i took corners real hard, they would flex enough and slightly rub the leaf. This was with 12" wide Prostars with (I think) 4.5" of backspacing.
