do all the variations use the same ring and pinion? im lookin to pick up some gears pretty cheap from a guy and his was a d70U and mines a D70HD. thanks guys

Which catalog is that? Because there are aftermarket gears available for the HD, my brother has 5.86s in his d70HD. I want to say they were precision gear or yukon.I found a different catalog. The Dana 70 and 70-u are interchangable the 70-hd is different it uses different bearings on the carrier and pinion and is its own beast. There is no aftermarket gears available for the HD that I could find.
