I've looked at those zoom clutches more times than I can count here lately while shopping for a replacement for mine. The one you need is 770-MU1675-1A. I too looked on both summit and jeg's websites, and summit's info seems to be all messed up. If you were going to keep the car, I'd recommend the zoom multi-friction unit (part# 770-MF1675-1A), which is really good quality clutch, but it costs about twice what the MU series unit does. If you're just going to sell it, just throw in the MU clutch, which is equivalent to the OEM clutch.
