Alternator

[Minkota]

What is the part number or car/truck year and model so I can purchase a internally regulated alternator. I tried using the part number shown in the stickie but parts stores tell me it’s back ordered indefinitely.

Also, what would be the best amp to choose for stock factory harness with A/C, electric fans, and aftermarket lights and radio. Just don’t want to burn truck up with too high an amp output. There is a possibility of going to dual batterie in the future.
