Help decode a 67 Barracuda

I dont see a stripe code. this would be best done with a picture of the tag. silver body with red interior and blue stripe, blue was not an option with red interior, only red or white. The rest of it seems ok save the abc codes are not complete. a6, b4 then just numbers un-associated with letter.

formula-s, 273 4bbl, 3.23 sure grip. does it have a 150 mph speedo also?
