Oh well. Turns out, just remove to screws at back and gently pry off. THat turned out to be the easy part. Dentless repair guy was making final few taps, hit rear window and it EXPLODED. Glass everywhere. He was more upset than I was.

Stayed calm. He called a glass guy. Will get OEM rear glass put in hopefully by Monday. Told me to get rental car if needed. I was upset, but I almost laughed. He didn't do it on purpose, he's replacing the glass, and acting like a jerk wouldn't accomplish anything.

Must be mellowing in my old age.
