Yep, I parted out a 74 Berlina that had the exact same parts, except the tinted glass was green. The most telling item was the molded underdash evaporator/blower assembly that incorporated the factory heater core.I really don't think so. I had a '74 GTV with Factory Air and it had a Piston style compressor mounted where the battery goes. The Dash unit was specially made to fit under the factory dash dash, and there was a special shorter center console....
Here's a pic of the underdash unit and short console from a recent FS post for a GTV in Idaho. I'll try to get a pic of the underdash unit that I have in storage that will show the moulded fresh air vent opening. I understand your skepticism but I'm 100% sure this is a factory item. I also remember looking closely at the holes in the firewall that unicornbc mentioned. They were definately punched and painted at the factory - not done with a Unibit or a Greenlee punch like aftermarket would be. There were lots of other details that convinced me.Any photos of a factory A/C setup?
I'm not sure about California but the rest of the states didn't have a smog pump in '74. But yes, the enormous original compressor was a pig. Could easily be replaced by a lighter, more modern one though.Thanks Bill S.!
Must have run like a dog with A/C and smog equipment!
