V-Belt help for my '46 Ford Truck

[Junior964]

Hello All,

I was wondering if someone had the same problem I am having with replacing the belts on their 1946 Ford Pick-up. I have the flat 6 (G) which has the two v-belts. in the green parts book it says the part numbers are:

2GA-8620-A (Gen)
2GT-8620-A (Fan)

I have tried everywhere to find replacement belts, but the ones that I have found are not tight enough, and the fan belt keeps chirping. I called Mac's and they told me to try a tractor supply place they sould have the size's I need. Does anyone know the correct size of belts I will need. I believe the gen. belt is 34 1/8" belt, but I am not sure. I have no idea what the correct size of belt I need for the fan belt.

Any help I would be very grateful!

Regards,
Jeff
