6 Volt Alternator belt

[klawockvet]

Anyone got a belt size for a Model A running a 6 volt NuRex alternator? The stock belt runs closer to the lower radiator hose than I like. A cross reference number for Gates or NAPA would be good as I am driving the Pony Express Trail from Mo to CA.
Thanks

I have the same set up and run the NAPA 25-20426. It is a cog style belt and some say it will run better on the pulley due to the pulley size.

Cool, exactly what I was looking for.
Thanks,

I'm running a Nu-Rex alternator and just put a NAPA BX-40 (cogged) belt on it, fit perfectly
