1972 Duster Project - Back From The Pasture

Thanks Mike, nice looking Duster. I was always partial to that color. The black hood on top of it really makes it. The plan is to do Jr's very similar but in blue.
We would still like to put 15s all the way around if possible. Perhaps a 15x7 will still work. I'm too used to the B Bodies where they are a little more forgiving. I'm finding that the A Bodies are a little more particular when it comes to tire and wheel combos.
JR is insistent on Rallys and the only 15 x 8s I can find have a 4-5/8 back set. We have the 8 3/4 SBP original diff in it. How close to the rear springs are you with that set up?
