Hello FABO, Hoping to get some help confirming that I have a 1963 Dart rear window. Previous owner pulled the window, and marked it. I have a spare 64-66 window to compare it to. (See pictures). The tinted window is the later one. The markings show on AS2 82. As far as I can tell, that’s not necessarily enough to make a determination. The window is about 42.25” wide at the top, and 48.25” at the bottom. Approx 18.75” tall. Happy to take any additional measurements that might help in the process.
