My newly aquired '83 280SL came with a plastic box (marked 115 0865 02 55) that may have held a first aid kit. I've seen this in e-bay pictures located on the passenger's side rear panel. Is that correct and how is it held in place? The side panels don't seem to have any type of mounts that mate up with the holes in the box. Any help appreciated.
