I used the search function and did a search for "remove door panel" and found the following as well as other descriptions. This is the one I used previously when I removed the door panel from my '91 300 TE:
The door panel is held by slide on clips. When removing, you have to take out the lock knob, bottom light, door handle, and the rear striker trim. Then the door panel pulls upward to remove. It is hard and can take a while to move it loose.
