I have a superformance #203 that needs a clutch. 351 windsor, tremec 3550 the current unit slips during full throttle in the higher gears. I will be replcing the unit in the spring and need some help with a ford part number or a clutch from someone else as a replacement. Will inspect unit for
oil or anything else in case of a rear seal leak. Someone commented that the springs in the clutch may have weakened as it was bought in 1997. Thanks
