Thanks for the link Jon much appreciated Rock Auto did cross my mind, Just remembered the trans is a 5 speed out of a 2+2 260Z would this change who you'd advise getting it from ?
I don't think the gearbox changes much, it's the flywheel and clutch collar determine clutch fit I think. so if you're sure they're from the the original car, you should just be able to buy the one from Rockauto for your car year.
