Dry Sump, pump drive help please

[RonR.]

Ford 351 Cleveland. NRC 3-stage dry sump pump.
Trying to find a drive unit that will work for me.
Any and all help would be greatly appreciated.
I plan on changing to an electric water pump.
I do want to run a mini alternator off the pump drive/crank drive.
What drive unit do I need? I have the ford Moroso one, but it will not fit inside the dampener I have.
Anyone have a few pictures they would share with their set up?
