I took this diff off my S2000 early last year and have had it sitting in my garage. It appears the crush collar collapsed some causing the pinion gear to come out of line and eat a few of its teeth. The LSD, ring gear, and front AP2 housing and caps is in perfect shape. The rear aluminum cover was punctured. Has 38k miles on it. Shipping wont be cheap because of the weight of the housing but I will get quotes for serious buyers. Looking for $115 plus shipping for everything.
