Debatable... but after all these year's, who really knows.

It is all true. My 72 Mach 1 has a pop open gas cap from the factory and it is an August of 71 build. My cap  has an Autolite logo and part #. The Feds mandated that Ford had to stop installing them as of January 72.I gather that Ford was using up what they had left over from 71. This is also why I do not have a seat belt light on the passenger side dash. They were required as of January 72 as well.

As I mentioned, debatable. One that I am not going to get into after all these year's...

There are a lot a variables and fuzzy lines involved when trying to figure our "Clydesdales" out. There were some early 72 Mach 1's that did have a production installed  71 flip down fuel cap. Just like the 72 4bl Ram Air cars, there is no realistic way to figure an exact date when the fuel cap change took place . When 72 production started the flip down filler cap was part of the Mach 1 package. In fact there have been some early 72 Mach 1's  with a 1972 "D2ZA-BA" engineering number although the original "D1ZZ" part number was never changed . Ford was still duking it out with Government over the 71 cap issue . There was a fuel leakage problem when the car was hit from behind or in roll over accidents. The 71 cap was revised four times and still did not resolve the leaking problem. All the revised 72 sales brochure and order guides I have (as of 1/72) show the twist style cap on the Mach 1.
Since several new Government mandated emissions and safety related laws were going into effect  January 72, the right side mounted seat belt light actually went into production 12/1/71 on the Mustang line.

No Officer...I really don't know how fast I was going, my speedometer stopped at 140!
