I think I found my vibration problem

No, you need the correct piece on each end of the crank.

well that is what I have along with a converter with no weights on it. Still coming back to the internals not being balanced and who knows what is in there. I would almost bet the crank is cast. don't know why he would have changed that because he wouldn't have had another one and no reason to change a cast for a forged one.
