A/C Controls Vs Heater Controls

[Baby John]

My truck did not come from the factory with A/C but the PO had an aftermarket A/C unit installed from a company called "Vintage Air". He did not replace the controls, but instead he just connected the bowdin cables to the factory heater controls. There's really nothing more than a temperature control, and a valve control that switches from "heat" to "Defrost" and maybe somewhere in between and a fan switch.

I'm looking at buying a stock A/C control. Question is...will it be a direct swap...as far as the opening in the dash?

I'd think connecting the bowdin cables to the proper location would be pretty simple.

I'd also guess that the fan switch would be a pretty simple connection as well.

Can y'all help?
