Hello my name is Dylan and I'm currently in the process of restoring my 1972 dodge charger 318. I'm looking for some info on the air conditioning panel, on the back I have these nipple ends that I think small air hoses connect to them to control directional air flow through out the system. It is the original a/c unit. If anyone can tell me what this part is called would be very appreciative and helpful.
