So I had a thought today, might be crazy but might work as well, I see alot about pinion angle, and thought how about two right angle gear boxes with custom driveshafts made? One attached to each diff front and rear then one on a bracket hanging off the frame, I think it might be allright if you could find a right angle gear box that would hold up, and have sliding driveshafts like a pto on a tractor, I dont have the means or a reason to try this but it was a thought that crossed my mind, what yall think?
