After all that time and work...
A pal had a vibration & I took the driveline out so she could take it to a NAPA service center for balancing. Turned out it was WAY out of balance, they added a lot of weights.
Re-installed, the vibration was worse!
So I took a steel strait edge & checked it over real good.
It was bent.
She had another shop make a new one & smooth as silk after that.
