Hi Matt. Again, welcome to the site. As I stated in your other thread, you have a 1967 6 cylinder coupe (as indicated in the VIN - 123377L126776) assembled in Van Nuys, CA. The build date of 12A indicates your cars assembly process was started the first week of December, 1966. The beginning of 1967 production was August, 1966, so your car is actually 4 months into the model year.

, but a real quick and dirty is it came with red exterior, red standard bucket seats and a tinted windshield.
