1972 4x4 thermostat housing?
 

Did the 4x4s that had the metal upper radiator hose have a different thermostat housing? If so what did it look like and what was the part number?

Reason I ask is I’m trying to install mine, but don’t think with the short hose at the end that goes onto the housing and the angle of everything that it would ever seal right.
