AC in 70 versus 72-74
I have a 1970 RT that has had the AC system removed. I have some of the ducts and the switches still in the dash. I need to install a heater/evaporator box. I have a 72 box available. Will the 72 fit and bolt into the 70? Are the vacuum controls the same? I have never seen a 70 box. What other parts do I need?
