I don't see how you're going to be able to use the inner belt unless you make some sort of custom "idler" that is driven by the outer belt from the crank pulley (which will also drive the outer sheeve of the dual-sheeve 37-48 truck pumps) and then it drives the generator/fan on a short belt behind it. You might be able to mount the idler bracket to the two front intake manifold bolts on each side. The idler will need to be able to slide to provide tension to the outer belt and the generator/fan can slide to provide tension to the rear belt. You'll not use the rear sheeve on the water pumps.
