74 Duster
Actually it's a GM alternator ( probably a 10SI) that someone transplanted on the /6 motor. Worked great and I wanted to use it on the Magnum transplant, especially since my new rewiring of the car included that alternator, so I didn't have to screw around with the wiring in that area. Mounted similar to a Mopar square back alternator except for the adjuster bracket which I had to fab up.
