I've searched on here and out on the internet and haven't found what I'm looking for yet.

A week or so ago, something caught under the passenger side of my C300, and pulled off part of the underbody (not sure what else to call it). I pulled off the loose pieces (a decent sized chunk under the rear passenger door, and a narrow piece going from there to just under the front passenger door). It seems to be fine now, but I was trying to find the part number and cost for replacement (it looks like it's all one piece under the car though).

Help please!

 

I would suggest posting a photo of the underside of the car so we all can get a better idea of what you are saying (pictures speaks a million words)
