It appears the power steering is leaking and husband believes we need a new pump any advice can we get it at the local auto store or could it be something else.

I would start with either taking it off or pics and go to the local napa and say I need a ps pump for my truck it has a (engine) and start there,pump should have a part number or data plate on it

i dont know where you are located, but any truck parts house would be able to order the pump or the kit, and as mentioned in a post above, you can also order stuff online, but many online places cannot cross reference the part number you need as it is on a bus.
As far as making something else fit from another truck, as long as the pump pressure is approximately the same, and the v belt the same, brackets are easily fabbed up...
