according to page 183 of my Ford parts interchange manual, the 69 and 70 fastback back glass is the same. Hey, the coupe glass is the same for both years also. The fastback glass has a NAGS number of B4120 and the couple NAGS numbewr is B3200. Of course the couple glass doesn't fit into the sportsroof without a glass stretcher and a lot of duct tape . . .
