update 3 years later, more photos turned up of the 1969 GT 500 test drive... it was a lemon and stranded them on the highway during the test drive (it was a Ford you know, found on road dead was an acronym it earned)

back in Dec 2013 I found and posted the above, not knowing it was one of 4 photos in a series
