--------------------------

Cecil, everything is back at the machine shop now. I have another M flywheel out in the shop that I could measure.
But it will need necked out 1 5/8" like the one in first pic. A 460 flywheel is too small, and 560 flywheel too big.
If I can ever get this figured out, I want to put a 301D in another old M with a bad engine.
If you think you may have something that will work. I will drive back over to the machine shop and get dimensions in the morning.
Thanks
