does anyone know if i can fit 17x7 inch rims on my 72 dodge demon the suspension has stock control arms and everything there all rebuilt though it also has .920 t bars if that makes and difference it also has 73 style disk brakes.
You'll have to get under your car and measure yourself. Every car is a little different, however, I *think* that a 7" rim would need 4.25" to 4.5" of backspacing. Tire size is going to matter also. You want to keep it under 26" in overall diameter for the front (someone correct me if I'm wrong), and you can go a little taller in the rear unless you want the sizes the same.
