Hi again everyone!
Quick question:
What fan belt size would be correct for my 1939 Ford flathead? The belt would cover both water pumps, the generator, and obviously the crankshaft. I tried measuring the old one and I got around 53 inches, but it’s a bit worn and not the most accurate. I saw some 52 inch ones online and was wondering would those work??

Let me know what you think is best.
Thanks!!
