Manual transmission Conversion. Have a new V-12 Flywheel from The Driven Man. I need bolt part numbers for the clutch pressure plate to flywheel. Unusual tapped holes in flywheel. The first 1/4"is 3/8”-24 UNF the remainder of depth of the hole is threaded 5/16”-24. Could this be a mistake? I read on line somewhere that the bolts are sold as six sets of two, but not part numbers listed. Any help appreciated. Speedster in Michigan
