High output alternator recommendations
I would personally recommend going to a Delco 12si alternator, you can buy one with 94 amps that was from a stock location and it has a single v-groove pulley. The brackets are easy, you flip the stock top one, cut off the lower leg, then you buy a GM universal one and weld it together to part of your original. Make a spacer.
For wiring, I would install this kit. It's overkill but its a good kit. You will want the squeeze crimper you use with a bench vise. I changed my car to a MIL spec positive cable and put another terminal on my B+ to the starter as well.

I have only a 78amp 12SI and this will run literally everything at idle (I have a contour fan, Aeromotive A340 Fuel pump, EFI computer) and maintain 12.5V at the dash gauge. That alternator is a basic parts store reman and has been on the car for over 10 years. I think I paid $55 back then. It's still a really low cost system, and if you need one on the road it shouldn't be much trouble to find one.
This was the thread from the original install.
