Post your wheel and tire combos.
So the wheels are 0 offset so I think the backspacing is something like 4½ in the back and 3½ in the front but don't quote me on that.. the rear is a b body 8¾ shortened to 55½ inches overall with Dr diff axles and front and rear disc brake kits (which I couldn't be happier dealing with him.. all good stuff ) I did move the leaf springs inboard to the frame rail, which was much easier to do than I thought and we'll worth it. On the rear I left the 3in studs with 1in wheel spacers to center the tired in the wheel well, that way if I decide to mini tub in the future I could fit a full 2 more inches in tire width, but would have to switch to 12in wide wheels of course. But we'll see.. these 275s are no match for the 440 and 3:91s
