I have tried searching but no luck. I am looking for a diagram showing the belt routing for a 73 300. The truck that I am looking at has AC (but missing belts), no power steering and it appears to have an idler pully with no belt just sitting towards the top left. The current owner does not know anything about the truck, but with a shop diagram or pictures, I would think that I could put all the pieces back together again.

Any help or recomendations as to where I might find this would be greatly appreciated.

 

Typically, the older trucks with v-belts will have the alt and water pump driven by 1 or 2 belts (dual alt belts is common on a 6 cyl without PS). Routing would be crank, alt, WP.
The A/C belt will go from the crank, over the idler, then the A/C comp. This one seldom touches the water pump.
