Vintage Air A/C system

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.

I've been considering the same option, the compact unit is small and should fit once the stock unit is removed. I'm about finished with an install in my '60 Starliner and install one in a '66 vette I sold a few years back. If you go forward, please let me know how it works out.
