There are lots of options an alternators but before you do ANYTHING read THIS

All these old girls are starting to develop wiring problems, actually, connectors and switches, not the wiring per se. The Single biggest problem, or two or three problems that guys are running into is a damaged bulkhead connector, and poor connections at the igntion switch, the headlight switch, and the switches themselves The rusty, corroded fuse panel ain't far behind.

When you add more loads, and more alternator you just make that problem worse.

I recommend

1---The large alternator of your choice

2---Bypass the ammeter and convert a voltmeter. Read this thread:

Use a nice big wire from the alternator to the battery stud, and don't just leave it at that. Read that MAD article, and inspect, clean, repair, or bypass the bulkhead as need be

3---Consider using a relay box under the hood to further reduce "traffic" through the bulkhead. I used a box out of a junker Voyager van:



This is a nice piece, and provides relays for ignition/ charging, pump, two for headlights (hi/lo) and spares left over, as well as on board fuses. I did have to rewire it as needed.

Bussmann also makes relay/ fuse boxes that you can "custom build" to suit yourself:
