I like your ideas. I found a way to use stock parts with AC and only had to drill one hole. It took a few tries to get the right belt. Do you just look at it and start playing with the parts you have? It seems like sometimes a few days later for me....the light bulb just goes off. Oh back to subject - use the ribbed belt. They last forever and if you use a big alternator etc it will be good. Nice work Z7. Mark
