You could control the max charging current of the alternator by monitoring current flow to the car and modulating the field current accordingly while maintaining the charging voltage.
That way you could prevent a 60 amp alternator from frying a 40 amp cars wiring system?
I don't know how you'd do that. If the wiring is weak, and the load, fans, pump. stereo, or even just a very low battery in the winter with lights and heater, the voltage will sag if the current is limited, and the battery is low.
So far as myself, I don't have a Mopar that I can presently daily drive. The fall/ rain/ winter coming season is here, and the 74 is a "dry day only" car. The Dakota/ Cummins are both "in the computer" tho I guess I could wire one up in the Cummins truck
