Axle holes for the shorter span are at the same rail level as the center wheel (no drop), and those for the longer span are raised about 1/8" -- the result is a chassis that can tip just a bit on the center wheels, effectively a slight drop.

I'm sorry but we haven't got a chance to look at this in CAD yet but has anyone looked at making a square chassis by cutting ~2" off each end. I am sure this will require new belts but are the front/rear axle holes available for this. This keeps the front and rear wheebase the same.
