B029 cars.

Hi Guys, I was reading the B029 Authentication Guide by Jim Schild and Larry Griffith and they mentioned that the Mule car was actually a 67 Formula S Fastback.
I found this very interesting, however I cant seem to find any actual evidence that this car was a 67. The pics I found were of a 68??
Questions;
1.Was it a 67 or 68? did they change it to look like a 68?
2.Did they just change the side lights to look like a 68?
3.What happened to this Mule Car
4.What was the original color combo? some say red and white while somewhere else says orange and yellow??
5.Yep you guessed it, if one of you guys has any color pics of this car can you please post them on here so we can all see. :)

As always guys, your assistance is appreciated.

Here is the pic's I found.
