Which one was quickest in 1972

I remember in Mopar Muscle several years ago there was an article about a 72 Road Runner somebody found. Car was too far gone. No drive train. But it had a fender tag that coded to a six pack and 3/8 fuel line. Even GAYlen got in on it and said it could have been the real deal. Nothing more ever came of it that I remember. Interesting to see stuff like that, but until somebody comes up with solid proof.......
