I know that the TIV engine is quite a bit different. But, By T-III engine
has a rear mount. Is the T-IV mount much different?

I have a T-III installed right now, pancake with FI.

Now you are scaring me. I was kinda hoping that the flywheel and bellhousing
was very similar. And The rear mount bolted up in the same way.

The T-IV engines I am looking at are still in the busses they started
in, and I have the choice of three, up to 74, I think? What
year did the bus get 2000cc? So, parts should not be a problem,
unless they are worn out or sat too long.

Am I breathing too many gas fumes here????
