Here ya go
try one of these, Gusset Jury hub w/ solid CrMo 12x180mm axle with 10mm flats (fits standard (vertical) frame dropouts). I have one on the way for my Big Hit, should have it either today or Monday, so I can post back on whether or not it works, but if the first pic below, Jury hub on an 02 Big Hit, is any indication it should be fine.
Whatever you do, do not try the Woodman Bill Extreme which has a 15mm axle with 10mm flats, it won't fit. The 10mm flats aren't really 10mm, more like 12mm and thus cannot fit into the dropout without major modification to the dropout area, which is a bad idea if you ever want to sell your frame later. Oh and BTW rear seatstays for Big Hits run about $130.00 USD (witout bearings, that's another story

), I had to replace mine after I made the mods to try and fit the Woodman and wasn't happy.
