Panel Clips
 

My passenger-side door panel on my 98 ML320 won't stay locked in - the plastic fasteners won't hold for some reason. Someone was definitely in there at some time in the past, as the plastic sheet is missing. I tried buying some universal panel fasteners, but they wouldn't fit or hold either. Anybody have a source for a clip that works and what size do I need? Thanks for your help.

About a buck each from the dealer.
