I watched that video a while back, and did not believe what I saw, and that was the cap with ears.
I have restored a bunch of the round caps over the years and looked at quit a few original cars with there born with assy line gas caps including 1970 Chevelle's that used the same "Round" Stant vented anti-surge cap.
I would have argued long and hard that the ear cap had not even been made in 1969.
Any thoughts on the one in the video ? Maybe a early engineering test thing ?
Shauger have you seen the video with the ear cap ? Interesting, never say never ?

I would also have argued that there were no gas cap ears in 1969.
And this is not a case of different vendors - these were all made by Stant.
All the yard cars that I was 100% sure were original and had been crashed back in the day had the no ears cap.
But who really knows for sure?
Hey that sure makes it easy, that one looks just like the cap they are selling at walmart today.... LOL
