    So something came up the other night on a Barrett Jackson auction. So the one guy taking about the cars pointed to a factory hole in the firewall on a 70 Super bird for the vacuum line to go to the headlights. He said only the Super Bird has this hole. Well my Roadrunner has this hole. I have enclosed a pic of the hole. In the finished pic you can see the red power wire for my amp going through it.
    I have enclosed a pic of my fender tag. Can anyone help me decode it for me?
    When I restore this I had no clue this could be a Super Bird.
    Thanks

          Since we’re talking about holes what is the hole in the lower part of the shock tower in the pic? 95E3F8A4-35AE-4666-B526-B68D4150A973.jpeg

            Last line of the fender tag:
            RM = Belvedere/Satellite - Medium level
            21 = 2 door Coupe
            N = 383 4 bbl
            0 = 1970
            G = St Louis Plant

            All Superbird VINs would start with:
            RM23_0A

            No Birds had a 5th digit of N, as the base engine ("smallest") was the U code, 440-4 bbl.

            I hope this answered your questions.

                The hole for the vacuum line plug is larger than the tach wire hole (below).

                Yea I had to chuckle when he said that hole is only on superbirds.....How about a 68-69 Charger with the same hole for the vacuum operated headlight doors? I was surprised too because Steve Magnante is usually pretty good with those facts.
