I should do that. I have entirely new wiring through out the car, aftermarket gauges, 4 ga wire running from the alt to the starter relay. Headlight relays, electric fan, Accel 300+ ignition, battery is in trunk, no radio. Just some info on what I have.
Well I tell the problem(s) I believe will occur with the March pulleys, a) the pulley is machined to fit the diameter of the opening of the mopar alt housing. Not altogether sure about the Denso b) the pulley (looking at your picture) will be out to far. But that is still questionable.
