I guess I am a little late to this party. I bought a 1967 GTX 4 speed brand new. I picked it up in December 1966 and drove it out of the dealers lot a week before Christmas. I had the dual snorkel non-CAP air cleaner that said 440 Super Commando on it. To finish up another post about the hemi parts on the 440 GTX, my car also had the 18 spline transmission and Dana 60 rear.
