alternator/voltage regulator advice

I think I will go with a voltage regulator from a late 70's model car (two wire mopar type). a new style connector for it, and a two field alternator... I'll probably stick to a 70 amp... I have no electric fans, just a plain ol' radio, lights, and msd box to run.

I don't want to tempt frying any wiring... I just replaced the wiring harness with a good solid one that has no splices, but is still forty years old. If there was no advantage to an external voltage regulator I was going to do the one wire, because I like keeping the alternator as far away from my harness as possible, but after talking to y'all and reading around some more, I see the LIGHT!

thanks again.
