Sounds like you are doing good things and getting good advice.

One subtilty I benefitted from in my experience with these stick automatic swaps....after marking the flywleen and crank from the motor you are going to be using just check the flywheel from that motor for balance.

3 our of 4 times it will be neutral.

If it is neutral now check the stick flywheel.

3 out of 4 times it will be neutral. If both are neutral you are golden....bolt it on and rest easy you are good to go.
