I'm trying to replace a damaged driver door side panel: Outer Finish Panel - GM (20933903). Below are photos of the old panel and replacement panel and a diagram showing the panel as part 22 among other parts.
I managed to remove a side exterior panel screw, back panel screw, and side interior screw (which I now think may be irrelevant based on closer inspection of the replacement panel). Photos below show the locations of each removed screw.
I don't know what to do next. How do I take off the old panel and replace it without messing up the seat adjustment levers? The old panel is still pretty securely fastened. Any help would be appreciated.
