Sounds like you have the disk in backwards..The center spline hub on the disk will stick out more on one side, than the other. The shortest side of the hub that sticks out of the disk, faces towards the Pressure plate...BE SURE you have a way to center the disk!!!! Do not fully tighten the clutch bolts down until it is perfectly centered! If its not centered, you wont be able to get your bolts from the flex plate to the clutch on, or they wont line up correctly..This is all I can think of, as to what your problem is..check it
