After breaking numerous D60 Ring and pinions I have come up with a solution. By using offset bearings, some grinding and the right parts you can install Dana 70 gears into a 60 housing. The design is such that no machine work is required, just the kit and some grinding. I've also built kits to put Dana 50 gears into D44s and I've put Dana 80 gears into a D70HD housing. The increase in Maximum out put torque is typically 2000 ft-lbs. For example Dana rates their D60 with 35 spline axles at 6000 ft-lbs, and the D70 is rated at 8000 ft-lbs.
