One year and four months ago, I replaced all three of the engine belts on our '76 Salon (350 4-bbl, P/S, P/B and A/C, no air pump) with Genuine GM parts; they use 3 belts.
Today, one of the belts broke and took the other two with it.
I am left with a few fragments and no part numbers. Of course, I did not record the belts' part numbers anywhere, and my GM Oldsmobile parts manual has been of no help.
If you have part numbers (or lengths) of these belts, please lay 'em on me! I don't care whose numbers they are; I'm certain that I can cross 'em over. Ideally, I'd like to buy some Gates belts.

 

Here's the pages from a March 1976 printing of a 1976 parts manual.

 

 

Thanks, Raider! I have the same manual . . . and I couldn't find those numbers to save my life!

 

Any time. Hope the pages can also help others looking for 1976 belt lengths.

Also hope your 76 parts book is in better shape than mine! Either they used shoddy paper or mine got stored really badly before I got it! Probably a combination of both...

 

The manual is in pretty good shape. I can usually find what I need there, but sometimes it manages to befuddle me.
