Hope you found something! Is it an AMC 15 or AMC 20 rear axle? AMC 15 has drain plug on the rear cover and 7-9/16" ring gear. AMC 20 has smooth cover, drain on front of housing, and 8-7/8" ring gear. Any Jeep dealer can get the gears, as well as most aftermarket suppliers. The Dana 35 is basically a copy of the AMC 15 and parts should interchange. The AMC 20 is unique, but the center is still used in the AMG Hummer.
