75dart sport, I'm looking to run the same combination on my 74 Duster.
I want to put 15x8 w/4.5'" backspace rallys, with 275/60/15 tires.
I have the tires on now with 15x7 rallys 4.125 backspace, and needed a 1/4" spacer for the tires to clear the springs. I assume that I'll need a offset hanger...
