9999, all apologies, I do not sign in as much as I used to. I was alerted to this thread by other members, and am just catching up now.
I do not have any more info on the black 72 Trans Am.
There were a few special order Trans Ams (as Lee pointed out). One of the things that's difficult to determine with these cars is the actual color the car was painted. Typically these cars just have a "1" for a paint code on the invoice. Without a build sheet, it's hard to determine what that special paint color was. In the case of the Adriatic Blue Trans Am, Pontiac used the color code "D", which was an RPO color on the 1972 Firebird (but not the Trans Am). In other cases, such as the Starlight Black 1970 Formula featured in Smoke Signals, the invoice code is "1" and the trim tag shows "- -" for a paint code. Starlight Black was not available on the 1970 Firebird line, which meant that it was truly a special paint car.
There was also a special order black 1973 Trans Am.
