Only an "A" or "K" code can be a true factory GT. Of course, not all "A" or "K" codes are GTs. The GT was a factory option that required an upgrade to an "A" or "K" engine choice.
Weirdly, a C code could be a GT in 67. Must be rare, I've never seen one. You could get A code 289 4V engines, K code 289 HP engines, and S code 390GT engines in 1967. You could get the C, A, and S codes in non-GT Mustangs. IIRC, however, the K code came only as a GT.

I had a 67 C code GTA when I was in high school. It was my first Mustang and I'd sure like to have it back but have no idea where it's at. I didn't think it was a real GTA at the time because like many I didn't think a GT/GTA came in a C code.
No. Many 67 390 Mustangs were not GT's. The factory determined whether it was a GT. The GT was the Performance Image Option, included the heavy-duty suspension (stronger sway bar and springs, HD shocks, 4-turn steering), grille-mounted fog lamps, stripes, "GT" gas cap, and stainless steel exhaust tips on cars equipped with dual exhaust.
VIN? No. The "GT" was not a collection of options, it was a single option package. For 67-up, all you need is a "Marti report", which will be the original factory invoice, and it will tell you if the car is a legitimate GT.
