i have a nearly new quaife diff as used in stohr and west cars. this is the autotec quafe unit that used a bolt on sprocket flange and vw cv flanges. it is the diff unit only, no sprocket flange or cv flanges. this is good for a spare, or to replace a damaged unit. the cv flanges can be had for around $20 each(i actually do have some) and the sprocket flange is around $175 new last i checked should someone want to complete it. i also have one that is in useable condition, but it came lose from the diff it was on and the holes were a little oblonged out from coming lose. this diff apears new, but has a couple hours of use on it from a shake down test. looking to get $500 plus s+h
