I'm not necessarily arguing, Jerry, but I've never seen anything but anecdotal evidence that the red and blue fittings were used before about 1975. A pic of any era car NOW is dependent on someone's statement that it was that way back when.

There ARE color photos of these cars in the 1950s and 60s. Those I've seen show silver fittings only, sometimes brass. In my experience, the colored AN fittings were new and kewl racer tech around the mid-1970s, not before. (My personal recollections don't go back to the Cobra era, but my dad was a racer in the 1950s and I grew up around various performance cars and engines, none of which had those fittings.)

I would genuinely appreciate a positive, non-anecdotal proof of red/blues in use in the original Cobra era. A dateable era photo would be sufficient. Even a good enough b/w photo would show something other than silver or black.
