Widest tire on early b body rear end
YOu can fit a 13" section width tire under there. A 295 is easy.
Spacers are fine. Just get quality ones.
YOu will never run a deep dish wheel unless you narrow the rear. Even an A body rear is too wide if that the look you want.
The narrowest rear you can go with factory framerails and leafs allows a 3.5" backspace wheels.
