70 rs/ss, since your burb for sale has A/C vents in the dash, I doubt that it was dealer installed. I've never heard of dealer installed A/C involving cutting holes in the dash for A/C vents. I hope someone would correct me if I'm wrong. Unless a former owner cut holes in the dash for the A/C vents, AFAIK, you can rightly claim factory A/C, but you will confuse potential buyers because your burb has a non-A/C heater core and box on the firewall and the A/C compressor and its brackets are not attached to the engine (or shown). I'm curious, do you have the A/C heater core and evaporator along with their firewall mounting "box?" And the compressor? In other words, except for the condensor, the burb looks like A/C within the interior, but non-A/C in the engine compartment.

If the build sheet does not say A/C anywhere, you might pull an in-dash A/C side vent to check if the paint is missing from a cut rather than factory painted thru and thru. If you see unpainted or repainted cut marks, you probably know a previous owner tried to install A/C. Also, do the dash vents have hoses running to them? No need to reply, I'm just curious. The truck does not lose value either way since the A/C is not hooked up and has missing parts on the truck itself (evap, A/C heater core, compressor & brackets, etc.). You still have a fair price even for a truck with absolutely no A/C components.
