to help the OP.
the clutch should be a 26 spline disc. the 3650, stock gt trans for 3v cars, that is probably in your car is 10 spline so it won't work with your 3650 trans.
the ENTIRE assembly, trans, clutch and flywheel will bolt in your car. as others posted you will need, not listed, a 6060 trans cross member to finish the install.
