What would you narrow a dana 60 to if narrower than an A body? 67 Cuda,no mini tubs planned,stock spring hangers. Stock 7.5 width is narrower than other A bodies anyway I think??
I narrowed my dana as far as you physically can with a mini tub. That requires a 3.5" backspace wheel. But like 72nblu said, you need to buy your wheels and then select your rear end width.
