My mechanic is going to install used 4.56 gears from USA Standard Gear in my TJ with Dana 30/35 axles. I received the gears as spare parts with the jeep and he said I need new shims and bearings. I think I should get a set of "master overhaul kits" but I'm having trouble finding the USA Standard Gear ones available. Can I use another brand of kit like the Revolution Gear ones for example? It seems like there shouldn't be any problem but I'd like to be sure, as the shipping costs will probably cost as much as the parts themselves. Thanks
