Is this thread going to become another math is hard deal?

The guy used a 15x10 with 5.5" of backspace. Then needed a 5/16 spacer. Let say 5.25bs now to keep fractions easy... Early axle ~3" shorter = ~1.5 less per side. So lets subtract that.

15x10 with about 3.75 backspace should be pretty dang close! LOL
