Hi Guys, I'm having a very difficult time finding a Flywheel ( Flexplate) for a 1959--FOM 3 speed auto tranny for a 292 cu. in. y-block engine. The flywheel measures about 15" in diameter with the starter teeth on the flywheel and the Torque Converter has 4 studs about 11 1/2" apart to bolt to the flexplate ( pic. attached). I can find one with 3 holes for torque converter. Can I buy the 3 bolt one and drill the holes required to bolt my 4 bolt converter to it?  Thanks, Tom
