From VanPelts > " Had the two fan belt system (beginning with 1942 models) to drive the accessories. One belt operated the water pumps and generator. The other belt operated the cooling fan assembly."

Does your car have this? - two belts?

There is a giant hardware store in Ephrata, Pa named Zimmerman's. The store
looks to be 4 or 5 acres in size. Inside hanging from the roof trusses is about
25 rows of V belts. The "B" belt is about the right pitch for the wide belt Ford
pullies. They have a web site and the belt lengths are listed. G.M.

I just monovered around Zimmrman's web site. It's a little difficult but you can
get to power transmission belts. If I recall I used a Carlisle Super ll V belt. It was
a 21/32 wide belt and if I recall about 42"s long. you can order them by phone or
online. I think they have a formula by measuring pulley diameters and distance
between pullies to determine length. G.M.

Measure the circumstance of your belt. Subtract 3 from measurement and that should be the size of the B belt you need. A B54 will be about 57".
