It looks like a Gates 340 or a Dayco 15340 but keep in mind that you need a matched set since they are so short. Three of the same belt will not work, you will end up with one tight and two loose. You are much better off buying NOS belts.

If you are buying belts from an auto parts dealer ask him if you can look at all the belts he has of that same number. If you can match the date codes/lot numbers on the belts he has chances are you'll be OK otherwise go with NOS belts. They're going to be a little stiff with age but will work just fine.

Well I ended up picking up three from ace hardware Mitsubishi general utility v belt 4L 370 I know this might upset the purist . But for what I use it for it will be just fine. Mainly show and veterans events, no off-road use but everything is running fine.

Purist or not a set or three originals are so reasonable .
Around $20.00 plus shipping.
Not worth worrying About non matched ones!

Only thing that worries be about some nos parts are age even new unused belts will degrade due to age and may wear faster than new. These belts were readily available @ under 8 dollars . I’ll see how these hold up if I see any signs of trouble I’ll replace with nos belts. Odds on all three failing at once are super low. But like I said I barely drive this one so I think I’m good I appreciate your input and will keep that in mind thanks

The belts will not fail, they just will not all engage the pulleys and therefor can cause charging and cooling problems. Not likely in a parade but out on the road at speed that fan has a LOT of resistance with the blade pitch it has and it will slip the belts unless at least two of them aren't tight. And if for some reason you need the full 60 amps for charging you will definitely need all three belts in contact with the pulleys evenly.
