Definitely was a factory original A/C car. As opposed to '68 and later, you did NOT get the rectangular center panel and dash end round air vents UNLESS the car came with A/C. Non A/C '67's, like mine, had no vents in the dash at all (photo). The corner door vent windows and side foot well vents were your cooling system.
If you enjoy the car - just procure a factory - like A/C system.
