All the car alternators have rib belts with the exception and some early 80's rear drive cars. You should just find the correct one that fits the brackets that Andy makes and save some time messing spacers and bolts.

Pulleys are cheap and I can get a car alternator guaranteed to work for $20. Plus I like fabricating, it's part of hot rodding IMO. Otherwise I'd just be a parts changer.
