HELP DECODING 1968 Barracuda Formula S fender tag/data plate

Another reason to suspect a problem is that 3 under the X denotes clear glass, but A/C cars were supposed to have all tinted. The 1 under the S is A/C, and the hose is right there in the picture. So that looks legit.
If the glass is clear and date coded, you have a car that "shouldn't have been."
