Why do 6.9s that were non ac have a dual vbelt pulleys on the power steering pump but 7.3s don't? I know 6.9s often would have 2 belts to spin the water pump off the crank but I've only seen 7.3s with an idler. Just seems odd. I'd love to run on board air off it but it's so much cheaper to do a 3g swap and use an electric compressor.

I put an under dash ac system in mine but still have that empty groove in the pulley..
