Hello, I own a 76 280z which is all bone stock, and the clutch is starting to really slip, almost undriveable, and a friend of mine offered me, his used clutch which is almost new, the reason being hes going to be making about 600-700 hp on his ls1 swapped 300z. But he offered me to have his old clutch because he just ordered a new racing clutch for his car, which was about 1700-2000$ and I was just wondering if a RB25 clutch would fit with the L28 transmission?? Thanks in advance.
