Door glass, tint vs clear

Well, I learned something new today :smiley:. My driver-side window does not have the “sun-x” etching on it, and it’s very clear. The passenger side does have “sun-x” etched into it, and it’s slightly tinted. I’m guessing my driver’s side glass was replaced by a cheapskate at some point.

Another question related to/regarding this topic. Where on the windshield is the etching located? I’m 99% sure the windshield is original to the car, but I can’t see the etching anywhere. Is it hidden by the chrome trim pieces? Where would it have been located?

Bottom center, definitely visible with trim installed.
