Dave, I'm all about converting to an alternator. I did it on both of my classic Fords.
But, I have a question: If you're going to do the conversion, why didn't you go with a higher capacity alternator?
Newer Ford alt's put out 130-amps (or more), perfect for an electric fan, and they contain a regulator inside the alt. They're also smaller than the original generator. Bone yards have lots of them from Mustangs, Crown Vic's, trucks, etc. (They're cheap and only have two wires (POWER-to your battery, and GEN LIGHT-to sense the key is on.)
Sorry guys, but I absolutely hate the 1-wire alternators because they don't work the way you would expect they should. Get a Ford alt.
Your alternator probably puts out about 40-amps. Here's your hookup:
