A 1941 flywheel is not a good fit. It uses 3/8" mounting bolts and has a larger center hole to pilot on the crank. I have seen where the bolt holes were drilled out for the 7/16" bolts, but the center pilot hole being to large is still in question... I know the three dowels will in theory keep the flywheel centered, but I wouldn't do it, unless that is your only option.
Any 1942-62 flywheel will fit. Just be sure to get one drilled for the clutch size you want to use.
