Old into New
 

I currently own a 75 cutlass supreme with the original 350. I bought a used running parts engine and tranny out of a 72 cutlass. The 72 has an ignition coil where the 75 doesn't. I plan on runing the 72 350 while i Rebuild the 75 for the most part(except donor parts needed from the 72). Mechanical stuff i can do but electrical is over my head. What will it take to run the 72 with the coil in the 75 car?

As an extra question
 

Will the HEI distributer unit from the 75 fit into the 72 engine to save the rewiring problems?
