OEM look 15x10 steel rims with custom backspacing?

No suggestions or favorite companies? :rolleyes:

I put new springs on ( 1964-1976 Dodge & Plymouth Leaf Springs | General Spring ) and the rear is centered better with more clearance to the frame/inner wheel tub, so I can keep the 8" BS for now.

What backspace is everyone running with minitubs and 325/50's? 7" or 7.25"? With 7.25 I'll probably have to roll my quarter lips.
