Rear End Swap 7-1/4" to 8-1/4"
I pulled the cover and inspected the gears. Everything looked pretty good. The motive gears I used showed quite a bit of tool marks after that black coating(phosphorous?) was worn off of gears during run in. This is probably what separates lower cost aftermarket gears from OEM quality gears. Pattern looked pretty good, kind of hard to tell from pics. The blackish color on the pinion is where some coating is still left, it highlighted the cross hatch pattern from finish lapping at the factory.
