Shawn,
The spacers the guys are talking about go on the six studs that the pressure plate bolts to the flywheel with. If you were set up for a .280 disc before and now have a .330 disc your air gap is probably .050 less than before. Basically your pressure plate can only open up the air gap a certain amount and if you use a thicker disc that certain amount is now less. Measure your old disc and figure out how much thicker the new one is. The difference in the disc should be how much shims you need. Hope this helps.
