Like you said, long time ago, but I know I had them on my '68 Bird back in the day when I got it from the dealer. If the compressor is on the car it should have the under dash controller. Most aftermarket products were controlled with a inflation valve in the trunk, or under the car. Last year I rebuilt the compressor on my '68 Sprint. There is no question that it has a AC Delco stamp on it. The old shocks on the Sprint were, best as I can remember, also AC Delco, But if the Koni shocks were black (back in the day) it's possible . The new ones are Gabriel. I run them at 30 Lbs & they respond well. Bump up to 60 & the rear end rises up for the "old school" look. Super stiff at that level. I know there is a stamp on the controller back, but I am currently installing a rebuilt engine & exhaust package. I'll get back on the stamp when I get back inside the car, after the outside work is done. As to what was in what when, it all came down to how good of a customer you were. My dad got a two tone Blue paint job ( light on top, dark on bottom ) on his new 1964 Tempest Custom. (Not in any of the books) Because his '55 Pontiac Chieftain had it. Had to wait for it, but to him it was worth it. Chevy had COPO. Pontiac had "If your willing to pay & wait you can change up lots of stuff."
