My SO, aka "the destroyer of Benzes" (wrecked my last 500SEL), has managed to rip out the plastic panel on the passenger side door by catching it on a high curb and pulling on the door. The panel is still held to the door from the upper attachments but is flapping like a doggie-door because nothing holds onto it at the bottom. What parts do I need to repair this? It seems like plastic holding pins were broken in the process...
