Mine is a factory AC car but their webpage is misleading. At first it reads as if the system is for non-AC cars only but down torwards the bottom it says " A/C, Heat and Defrost. For non factory air & factory air vehicles."
I did email them several weeks ago to ask this specific question but never got a response from them.
the blower motor hole is larger on the a/c cars, but no biggie. i think it's mostly because of the heater controls. the classic cables use the non a/c heater levers, where the a/c controls are vacum controlled.
