My car left Dearborn wearing Magnums. The only Mustang, that I am aware of, that ever wore the KH Magstars was the 1967 Shelby. (I don't know if they were ever offered even as an option later, given the rivet problem.) The desert car was generally considered by most to have been a styling exercise, with non-standard wheels and striping. For years, a lot of people called it the "Boss Prototype Car."
I have spoken directly with people who worked for, and continue to work for the company that prepared Ford's cars for the west coast car shows back in that era.(DST or Dearborn Steel Tube). Yes, they are up there in age now, and may now be retired or gone since our conversations in 2007. They actually laughed when I mentioned the Magstars, the seat color and missing quarter window in the photo. They said that was very minor considering some of the things they would do for an advertisement, or prototype, or styling exercise, or for display at a car show. The car would then have to be "brought back to standard" if it was to be sold to the public. Rarely were they destroyed instead. We're not talking about plant cars or engineering pieces, just cars shipped and used for marketing and shows or styling exercises.
There's even more ie: it looks like the lower decklid stripe may be painted on. There is a small area on the right quarter extension that is exposed, and looks to be a thin painted stripe. Some of the Grabber Yellow is definitely repainted. Look at all the dings and dents. That's why I mentioned the "33 years in the wild."
Realize this: It is also not known where the car was and what it was used for, from the date it shipped until late winter, when it was the subject of the Official Communications Memo. We do know they referred to the car as "one of your (Dearborn) show units". How many shows? Don't know. What changes to its appearance after the official BOSS 351 was released in November of 1970. More striping changes for more shows ? Don't know. The Car show circuit ends around February or March. This car was released for sale in late March 1971.
The point being, there is no reason to expect the car to look the same as it did in the desert photos after it was used for this kind of purpose. Someone mentioned the Magstars. I have a set in the basement. 20 lugnuts, no big deal. Anyway, absent an actual VIN or Marti Documents to prove differently, you're just guessing about test mules without motors, missing drivetrains, color hues on monitors, tape or painted graphics, airbrushed or real, etc. Believe me, I have been looking at all of this exact same stuff for about 10 years now. I respect Kit's and everybody else opinions and observations, but not a single thing here is new to me in this thread. And, I say that respectfully.
I will say if this car, that was built as a 1F05R, is not the one in the photo, I've yet to see another one so built. But everyone has a right to their opinion. Even me ! Cheers everybody!
Well, here's the blue Boss 302:
...and here is a B&W shot from Car and Driver's Boss 351 test:

Clearly, these are the same vehicle...once a BOSS 302, then later a BOSS 351. Even the valve stems are in the same spot in relation to the letters on the tires!
I would love to find this car !! I look at every eBay ad with Medium Blue Metallic/ Argent Silver.
Here's a copy of an email I received from John Kranig, retired Ford Engineer. You guys can throw this into the blender, since we are also talking about the blue car:
Hello Andy, My name is John Kranig. Thank you for the extra web links. I am currently in Florida so it will be a few more weeks before I will be home and able to search for those pictures of the 1971 Boss 302 engineering prototype. As I remember that car's color was either light blue or silver. I'm quite sure that car and any other Boss 302 prototypes built for engineering tests were destroyed after no longer being needed as was the requirement as they were not allowed to be sold to the public.
The engineering prototypes were built with prototype parts on non-production tooling. Your car on the other hand was built on the Dearborn Assembly line with all production parts so it was legal to be sold even though they had to change the engine as the Boss 302 program was cancelled but the remainder of the car was ok.
I'll get back to you some time in April whether I was able to find more pictures or not. I'm glad you found the information I provided interesting and I'll try to remember or uncover more in the future.
John
I did not receive any additional info from Mr. Kranig afterwards. You guys type too fast. By the time I can compose a reply, you're 3 more posts down the page ! LOL ! By the way, is anybody NOT in Florida ?
