Gotta a pic of the car?
The 2 indicates two of the possible 4 molding options - however you could only get a combination of 3 of them, never all 4.
I looked at so many cars this past week that I can't remember one from the other, but I did see one at the NNN show that had a number on the tag indicating multiple moldings. The owner claimed no BS option, till I showed him the remnant clues
BTW, my '69 has a '3' on the tag for DR, DF, and BS - but no vinyl top!!
