Finally got it off. It took 3 days of soaking with pentrant and tapping with a hammer (very lightly just to work in the CB Blaster)
Had to drill out the old bolts, and put it back no problem. In other posts they said that it would rotate when re-installing, but mine did not? Oh well all is good on this front now at the other end of the motor, got to put in a new clutch.
