I am trying to remove the rear door panels on my 1987 560SEL. Can anyone help? I started by removing the window/seat heater/seat recline switch, as well as the trim that goes up from the top rear of the panel to the top of the door. I removed the screw at the bottom of the panel and the two screws on the door handle. Now I'm stuck. I figure out how to fully remove the handle, what else do I need to do?
