choosing the right alternator

I am looking to do the same set up you talked about. What wires at the bulk head connector did you ditch ? What do you need ? I will run a GM alt and a MSD box with a mopar electronic distributor.
Any pics
Thanks
Basically it was everything for the electronic ignition and the factory alt wiring going thru the bulkhead. Just find the ends your not using and follow them back to the bulk head and remove them.
