1978 Alternator

What is the strongest alternator that will directly bolt in and wire up to a 1978 F100 with a 460? I dont want to modify the wiring.

I'm not sure of the year/engine combination. It may be a 60 amp or a 90 amp. I'g take it to an alternator shop and have it rebuilt to 100+ amps. It's a simple do and doesn't cost that much. (cheaper than buying a new one)

Thanks. If I have the 90 or 100 amp alternator will I need to upgrade the voltage regulator?
