Cutting ring and pinion gears is quite an undertaking. I recently contacted Richmond Gear about a reverse direction gear set for a Corvair transaxle. They can do it in most any ratio I would like but I would have to buy about 50 sets at over $600 per set. Needless to say this thought went away pretty fast. Running the gears backwards by reversing the engine rotation is an option but the gears are running on the coast side of the gear and exert tons of side thrust and can destroy the diff case. Getting an engine to run backwards is not difficult, the boat guys do it all the time in twin engine boats.
