Well..... I went ahead an ordered my PHS documents. The best I can tell, they indicate the car did NOT come with factory A/C:



(PHS photo also attached to this post)

So, now I'm not sure what to do. I have some experts here telling me the A/C is factory, and the PHS documents saying the car did not come with A/C. Any way to know for sure?

Can you post a photo of the billing history form, too? And what's listed in the axle identification box on the power train form?

Attached is the billing history form, and the power train form.

Also, here are some photos of the interior (showing the climate control panel and vents) if that will help.

Well ya got me stumped! Totally looks like a factory installed A/C system, but there is zero indication on any of the PHS docs stating that it was born with A/C. Even the axle ratio is wrong for an A/C car. Pretty mystifying, because the difference in the firewall configuration between an A/C and non-A/C car is pretty significant. And you have the larger HVAC control panel and vent cutouts in the dashboard. It's hard to imagine all that stuff being converted afterward, but here we are. None of this makes any sense to me. Nobody wants to think about it, but could this car have been VIN swapped at some point?

In this day and age, I wouldn't rule out anything. But if someone did swap the VIN tag, wouldn't they have to have found a car (or VIN tag depending what they possessed) with PS, PB, Auto Trans, correct axle ratio, and with matching exterior and interior colors?

I think it's pretty unlikely that the VIN tag was swapped, but I have no other ideas on why your GTO has A/C but no supporting documentation for it. I'm not saying the VIN was actually swapped - more just that I'm stumped. Maybe others here will have some more informed ideas to consider.

I've seen stranger things. If I remember correctly, there was a thread not that long ago where, on the member's car, the firewall was changed at the factory. Seemingly at the last minute to accomodate AC. I'm talking about cut with a torch. I'm not sure if it wound up on the trim tag. I'll have to find that thread.

Does the VIN tag in the door jamb have rosette rivets
Or basic standard hardware store rivets

Here is a photo of the VIN tag.

I found the thread that I was looking for. So if the car in this thread was discovered to not have an AC firewall and they modified it, what are the chances that they discovered the OP’s car had an AC firewall that wasn’t supposed to be? So they went ahead and installed it.

I worked for a guy awhile ago that converted a couple of GM cars to AC, using all factory components. It was a ton of work, but he was a perfectionist, and the jobs ended up looking like born-with installations. The tell here is the steep axle ratio and only tint on the windshield....a factory AC '67 would have the 2.93 rear gear and tinted glass all around. I had my '65 GTO for many years before I bothered with a PHS and found out somebody had added factory power steering----I never suspected it was originally a manual steering car. But that is a LOT easier than adding factory AC. My bet is that it was done early on when factory parts were easy to get. To do this conversion now would probably cost you 4 or 5 grand. Enjoy the AC!

According to the PHS docs above, the axle ratio for 400HO cars with A/C like this one is 3.23. Looks like non-HO cars with A/C got the 2.93s. Either way, the rear end in his car is incorrect for an A/C car of any flavor.

Thanks to all for the feedback and information. As of now I am going to conclude that the air-conditioning is not factory installed, and was a product of a really good aftermarket install, many years ago. Thanks again to everyone for the help.

Just as clarification, my '67 is a YS Automatic, factory A/C, 2:93, etc. and I have the PHS for it. The car doesn't have ANY factory-tinted glass and it doesn't show any codes in the "Soft Ray Tinted Glass" box 53 on the PHS documentation.

I wish it did have tinted glass, but tinted glass isn't an indication of a factory A/C car.
