1972 Demon Sunroof Survivor

From the picture on the website, it's pretty difficult to see the actual roof. As far as the statement of "1 of around 100 Factory folding sunroof cars", do you have either Fendertag code or broadcast sheet code that specs the sunroof? From what I have been informed of by the original owner of mine is that this was dealer-installed. Thx for any further info.
