I bought an aluminum Scheifer flywheel years ago in a junkyard and don't know what it fits. A number "500" is stamped on the back. It has 145 teeth on the ring gear. OD (including gear) is ~14.5" . OD of the wheel (not including gear) is about ~13.75" . Crank hole is 3.18", with 6 bolt holes and 1 locating hole. Crank bolt pattern diameter is ~4" . Holes are drilled for a Long-style clutch. Help.
