BackSpace question with a B-Body 8 ¾” in an A-Body Duster

Yeah it's too bad that the 17" rally's and magnum wheels that year one sells don't come with enough backspace to run on the front of the A-bodies...

The 235/50/17's are pretty easy to find because it's a stock Mustang size for the newer cars. 245's are hard to find in the right height, which puts the 255's as the next best option. I really don't think the 255's qualify for "steamroller" status, but obviously you can get a pretty decent handling set up with the 235's, the new mustangs handle pretty well with them.
