Can you see where there may have been a decal on the window ??? On my 70 Sport Satellite with factory A/C, there was no indication on the 1/4 window of the sticker - and I know the car was never touched before I got it. So I have never put the sticker on the window. My car has all tinted glass, as most A/C cars did . . . does your Cuda have tinted glass ???
