I think Chrysler alterators kept using the "external regulator" design even into the Denso type ones (2 field wire terminals). At least my 1996 2.4L is like that. But, you won't see the regulator since integral w/ the engine computer (I think), but no reason you couldn't use a 1970's Mopar Vreg that I can think of, and external is my preference (easier repair and trouble-shooting). I don't know which ones mount easy. The Magnum engines started using a large aluminum casting for all accessories, so can't use that unless you go to a full serpentine belt setup.
