Does anyone have the part number for the stubby hose between the thermostat housing and the water pump on an 81 SD? I'd like to order the part, but I don't see it listed in a way I can find it.

Is there any trick to replacing this hose or is replacing it as simple as removing the radiator hoses and the two bolts that hold the thermostat to the head?

Thanks,
Sixto
