Jim, these cars were from the DT&I, and the GTW purchahed the DTI from the PC estate in 1980. So the earliest the would have been GT blue is 80. Bill
Yep, Bill is correct, I neglected to see the GT car was the DT&I number with a 1 added when it went to the GT.
T-Bird will have to removed the old COTS label and put on a new one as these cars never had the single panel COTS.
I did a little looking into the GT logo 60' waffles to see if they were good for earlier than 1982, but thought I had read somewhere that they went to GT aroudn that time (1982), hense the 3 panel stencil. I know some models are actually good for earlier but the manufacturer put 3 panel stencils on them but they can be back dated. That kind of goes against traditional decorating as usually the manufacturer lables the car consistent with when they were built. (i.e. what ever labeling (ACI, single panel, 2 panel, 3 panel etc. was current when built).
