9in axle length

Yes, it is a custom width wheel 10.5 inches bead to bead. It was the closest i could get to 15x10 with a 4.5bs. I measured between 50.5-51 inches total to keep tire out of the outer wheel tub. The inner tubs are sheet metal and flush against the stock rails. I keep coming up with the same axle measurements with the 2.81 wilwood brake gap. The chart would be nice to see. I have heard that a 325/50 fits well with a stock length rear end with a 15x10 7.5bs.
