Just for some info on Richmond's, I just talked to a Richmond rep last weekend about this same thing and he told me that the only gears made in the USA are US gear and Richmond,  He also said that there are only a few gear manufacturers that make gears and stamp different names on them IE, Yukon precision etc.  I know this has already been said I just wanted to give you the info I was told by a Richmond rep who really seemed to know a lot about this stuff.
