later model 78 amp alternator?

CAVEAT. THERE IS NO WAY I would install one of these without doing some sort of WIRING UPGRADE. There are many many posts on ammeter/ bulkhead connector failure

"Ma" knew this was a problem which is why Mopar implemented the so called "police / fleet/ taxi" wiring mods for optional 65A alternators, AND WHY cars later (starting with some of the early 70's "big girls" like fury) ---went to an external shunt ammeter, which greatly relieved the bulkhead connector of high current, and ENTIRELY relieved the ammeter
