I've never seen a replacement part listed for the bushing inside the 2nd gear. It's pretty thin and getting a new one in there without damage could be problematic. Reaming could also be difficult with such a large bore. Some of the late replacements don't even have the bushing in there. This may be the reason Mac VP has been using the 81A-7102 2nd gear as a replacement for the later 51A-7102 part.
