67 Dart-upgraded alternator

I was doing a little reading about alternators in this forum. When I restored my 67 Dart I upgraded my wireing harnesses with new wire if needed. When I installed my electronic ignition system, I also upgraded my alternator to 78 amps-I purchased one for a 85 Dodge Pickup D100. It fit with out any modifications. Seems to be working fine. I thought about higher amps but did not see any purpose to do so.
