Thanks for the compliment on the car. The car sort of falls into a "gray area". It is the first "production" GT 500 built; but it was also an "Engineering" car. The engineering department had the car all the way into 1969. I would love to find out what all they did with the car while they had it in engineering, but do not think it will ever happen.......
That Cougar document you have is a great conversation piece. Pretty neat to have that I am sure.
