The trim tag posted shows a V8 car.
There is nothing on that trim tag indicating a V8 car.
Field c - body style code 12xx7 (See also this explanation of why the Fisher style and VIN prefix differed.)
The two digit year ("67," "68," or "69") was followed by a five-digit "ST" body style code, e.g. 12437. The first two digits of the style code are the model code ("12") and the last two digits are body code ("37" for coupe and "67" convertible).
While the Fisher style code is often confused with the first five digits of the VIN, the two codes are different because of the different meaning of the third digit. In 1967, the third digit of the style code was set to "4" for standard interior or "6" for custom interior (e.g. a style code for a 67 convertible with custom interior would be 12667). In 1968-69, the third digit was fixed at "4" for all models (L6 and V8) and had no meaning.
