Back in about 1998 I installed the Vintage air automatic temperature control on the stock heater/AC unit. They do not sell this system anymore and have replaced it with something newer, maybe the unit you are asking about. What I had to do was fabrcate mounts and belcranks to connect vacuum pull units to operate the two doors in the heater unit. I understand that their new controls are all electric and may be easier to adapt.
