Larry,

Here is a link to a collection of V-belt info over on the Resources section of the new Forum.

After trying a number of automotive belts listed as correct, but none were right...

I went with Industrial belts. They are a bit wider but that is better than too narrow. Two years later and no squealing and they are still running tight. I got them at TSC Stores (now Peavey Stores)

Go to the page and hit "Download" at the top left.

The belts used in our GMCs would be:
Alternator ‐ A56
Power Steering – A44
Air Conditioner ‐ A61 or A59 for the 403 engine
