my clutch decided to take a crap on me so i have to replace it.how do you replace the pilot bearing for the input shaft? is there a special puller to remove the bearing?. also can i use the stock pressure plate with a centerforce lm clutch disc?.i had the centerforce clutch and pressure plate in but it looks like the pressure plate is screwd up also.flywheel i think i can salvage,needs resurfacing. this is a cobra motor and t 56 transmission.
