The Ford Barn - View Single Post - Replacing standard pressure plate with early V8

The proper bolt for the pressure plate has a round, unthreaded shank or shoulder below the hex head that passes thru the pressure plate flange and a slight counterbore in the flywheel face. This does two things, locates the pressure plate and provides additional shear area that would not be present if the bolt were threaded all the way to the underside of the head. I know that Pioneer and possibly ARP offer the correct bolts, as well as some of the regular suppliers.
