Be sure to get and use a clutch realignment tool when you install the clutch. it is used to align the pilot beatring in the end of the crankshaft with the center of the transmission in put shaft. it will resemble the input shaft on the transmission (have the same splines and a male diameter to slip fit the pilot bushing diameter). You should not toghten the pressure plate to the fly wheel until you have it alligned properly. If you do you will probably not be able to get the input shaft inserted all the way in. iF this was a Ford or Chevy i would definitly advise you take it apart and see what you need before you buy parts. You may only need the trrow out bearing. I have never seen one on a crossfire but on a Quartermaster racing clutch set up it resembles a dounout that the transmissino input shaft goes thru. It expands when hydraulic pressue is applied and pushes against the pressure plate alowing the clutch disl to move at the same speed as the transmission input shaft.
