Funny noise

I had all 4 ears cracked and I got it home. I didnt even know it until I parked it and was so annoyed by the new trans noise that I raced it in neutral and shot a broken piece out the bottom, off the street and back up into the floorboard. scared the **** out of me. I got under there and removed the flex plate bolts and every ear fell out.
It was then that I found out about the 'T-flite Paddy' covertor bushing for an old trans and a newer motor.

Can you tell me more about that? I have an older trans in my Duster. I do have a new bushing installed. The front pump (I think) and clutch pack and shaft are for newer 727
