Does someone have a diagram of the vacuum connections for a 70 with factory A/C? I'm working on getting my A/C going and none of the vacuum lines are conected to anything. It was like this since I bought the truck. Im replacing the evaporater with one that has the oriface in the inlet. I got it out of an 87 Oldsmobile station wagon. It bolts right in to our trucks. Someone can have my old evap, expansion, manifold hose for free if they want it. dont know if any good or not.
