Strange Pilot/ hub size on 8.75 Rear drum brakes

Yeah, the trouble comes with finding replacement parts in a pinch, or going disc brakes down the line. It makes more sense to do it right the first time and find the correct brake parts rather than chasing down a million different leads, re-drilling for a bigger pattern, etc. It's not that it's "too much work", I think it just makes more sense to do it right the first time :)

The axles came drilled for the Big Bolt Pattern only, and the center register was for A-body brakes (Small Bolt pattern style with a re-drill) but the drums were from a different application originally.
