Does anyone know who was the previous owner of my car?

Yeah, I'd have some questions about the A/C unit too. First one on my mind is: What A/C unit? Do you mean the 60/40 unit?

Also, I would never post my entire VIN number.
That's just it, I don't know what A/C unit was planned for this car. The is a partial unit installed under the dash and you can see that the connections and wiring seem to be ready for the compressor and hoses to be installed.

Also, for some reason, I cannot delete the photo of my vin #.
