Classic Auto Air in 67 Barracuda Factory Non AC
Ok, so I just called them.
So the new system uses the same factory sliders, but have integrated potentiometers that connect to a electric water valve and servo on the box.
He confirmed you CANNOT retro fit an existing perfect fit system with this new setup. They will not sell the parts individually. I asked what if something fails, he said they would sell the parts, but I think what he was getting at was he wouldn't be able to support it or have instructions for a retro fit.
Also, the Bluetooth is only for diag. It doesn't control the system via Bluetooth.
