Highest Amp Alternator For a 72 Duster

Laymen's terms mopar has poor wiring and if you pull lots of current/accessories through that little black firewall junction you better be ready for a weenie/marshmallow roast. You have to upgrade the system with the links above. There is no way stock mopar wiring is going to handle what you want to do. You might pm member 67Dart273 as he is where I got the above links and he is very good at mopar wiring.

The wiring in a 60's mopar would by today's automotive standards have been recalled after 6 months for being defective. You have to update and upgrade it.
