i have a 69 gtx with ac, i have rebuilt my heater box and heater controls, i want to make sure everything works before i remount in car. did b bodies come with a vacuum can in the engine compartment or does it pull vacuum straight off of the engine. i guess 18 inches vacuum should be enough to work all the accuators. can i check the box out by hooking vacuum up to the supply hose?
