hey so i have a 5 lug 8inch from a 70 mustang in mind, but i looked up the length of that and it is 67-70 Mustang 59.25 inches so what does that mean for wheel fitment im guessing i would want to run a wheel with like 6 inches backspacing (like maybe the new mustang bullit wheels) but then how would i make the front work? any ideas would be helpful
