Anyone running 15x6 or 15x7 rear wheels on an early-a?

Good information, guys. I bought a set of 15x6 steelies that I'm thinking of having custom widened to 8" by adding the two inches as backspacing. I figure that will give me good tire width while preventing the notorious rubbing problems us early-A guys and gals have to deal with, and I get to keep a semi-stock look to it. Fzmax, I gotta say I love the stance on your '63.
