ALWAYS have the flywheel resurfaced. And make sure you use loctite and a torque wrench when reinstalling the flywheel. Remember it will only go on one way. Also make sure all 3 PP alignment dowel pins are in place before installing the PP and disk. The clutch will chatter like a bitch if you do not. My clutch chatted bad after a month of driving because the guy I bought it from lost one of the dowel pins that go in the flywheel and I had to buy a whole new flywheel bolt and pin kit.
