Been looking for a flexplate for the motor going in my T, a Pontiac Super Duty four cylinder, with a real unusal crank flange. It dawned on me that i have a couple of Quartermaster 7" multi disc flywheels lying around,( I think they are forgings), that fit. The question is would it be practical, and safe to machine off the clutch facing and use one for an automatic transmission flexplate? Would there be stress risers from the lathe that would be detrimental? Any real world info would be appreciated,is it a dumb idea or what?
