Are there 2 different types of A/C heater controls available for a '63 starfire as I see lots with 2 sets of vacuum pipes, 1 set for the temp lever and 1 set for the push buttons. I'm sure the one on my car only has 1 set with 7 hoses. Are these interchangeable? The chrome is shot on my one so needs replacing. It is A/C and not just ventilation
Thanks for your help
