V belt - Kind of triangle shaped. The pulleys make a V. You typically have 2 or more of these - 1 one power steering, one for alternator and water pump. These are manually tensioned with a socket wrench or prybar.

Serpentine - Flat with ribs. Typically 1 belt for everything. Usually tensioned by a tensioner pulley.



Since you don't have AC, I would go with the 78 amp alternator and call it a day. Almost double the amperage. Should bolt right up with the same wiring. I would be looking at the ACDELCO 3351094. This is a new alternator, so no core charge. According to RockAtuo prices, remanufactured alternators cost about the same as new. Prices can vary locally though.

If you know what kind of lights you are going to use, or about what you are going to use, you can add up the wattage to see how many amps you need. Remember to add in factory lights - headlights, tail lights, side markers, and anything else electrical you may be running - radio, HVAC fan. This can give you a good estimate of how much power you will need at a given time.
