Another advantage of using a 63-80 amp GM alternator is that there are rebuild kits and one wire conversions available for them. The alternators are mid '70s to mid '80s and are cheap from salvage yards. Grab the smaller brackets and it may help on the clone install too. One thing to remember in choosing an amperage is that cars used to have: a heater blower, high/low beam head lights, tail lights, brake lights, radio, wipers, dash and dome lights and maybe even trailer lights- all running on a 80 amp alternator.
