125-200cc Looking for a rear hub part #8000 96937 in the US

A friend and I are in the process of making another CR 125 into a WB165! I am looking for a rear hub, or wheel to buy. I would prefer a Hub as I have an 18" rim that I want on my own bike and would simply trade my 19" assembly out. I also have a number of 2001 -2010 parts to sell and trade. I have several tail pipes FMF and Factory, At least 1 front brake assembly, new front and rear sprockets, a TMX carb, Steering stabilizer, factory triple clams, a 2006 CR 125 frame with title, and a set of 45mm Marzochi forks with a short spring for a super moto application. I am also looking to buy a headlight assembly for the WR.
