The styled steel wheels from Stockton wheel for my 1965 Mustang Fastback with a stock 5 eye leaf with a one inch lowering block and stock drums in the rear. I just wanted to double check which backspacing that I should go with. Should I do a 15" x 8" with a 4.5" backspace, or a 4.75"? Stockton will do any backspacing, and I just need to know what will work the best. This wheel needs to be able to accomodate a 235/60/15 BFG Drag and clear the fender with no modification. Thanks again guys.
