Air conditioner compressor belt.
«

I have a 1974 chevy c10 stepside. 350 engine with air. The air conditioner belt is somewhere around 58 inches. Does anybody have a part number for that particular belt? It goes around one of the harmonic balancer pulleys, and the power steering, and the water pump and the air conditioner compressor. I am buying a belt at a time to get the right one but if someone has a part number it would make my process faster... Thanks for any help....

If it is a stock setup, you can get one at any auto parts store. Search for it online.

You can look at belts by length at the local part stores. That is what I did. If your used belt has a part number look it up, if not measure it and then look at belts by length. I attached a pick of my a/c belt with a Gen Air system. It was 59 5/8". I bought it because of the length.
If you go the Gates Web site you can look up the belt by length.

Other manufacturer's may do the same thing. I just looked at Gates products.

Gates says the factory outside measurement is 55.29, Dayco says 55.07, but if you want a custom size, you could order a 15580 in Dayco, or 7580 in Gates.

I don't know why this setup is not some standard part. Truck has been through many hands over the years. I have a few belts on order from amazon. I will just return the unused ones. I should be able to narrow it down by installing just a couple. Measuring says 58 inches but 58 was too big. I have half inch graduations on order down to 56 inches....

Does your truck have headers?

No headers thank you. I ordered a series from Amazon and returned the ones that were too long or too short. Turns out I need the 7570 which is just over 57 inches for my configuration, which is probably some mix of years. Thanks all for your help.
