I have a 72 Charger and I am trying to replace the door locks. The door panels are original and in great shape so I am trying my best to keep them that way.

I can't seem to figure out how the door panel is removed. It is a thin piece of plastic and it doesn't seem to have any screws holding it on. Does it just snap on and off? Or am I missing something? I really don't feel like paying a lock smith to come out and do a basic job.
