Rear bumper clip

[ALL500]

Hello,

So unfortunately my rear bumper has become detached on the right side. There is a rectangular clip that holds the bumper panel to the body and the plastic is so brittle it just snapped to bits. I think that rectangular piece is easy to replace, however, the piece that it attaches to does not seem to be.
On the inside of the bumper, there is a triangular-framed plastic piece that is normally fused to the bumper on the 300e. It appears that the one on my 500e is not fused but rather held in place via two small screws(?) on the top and bottom. I cannot find this piece at the scrap yard or online and the dealership does not have a part number.
Matter of fact, it does not show up on the diagrams that the dealer shop possesses.
If someone knows what I am talking about, please chime in, I have my bumper jury rigged with some wiring and duct tape!
I would like to get a proper part replacement asap so I don't have to do some kind of second rate, cement/glue job...

Please provide a picture to clarify.

Can you identify the item from any of the pictures in this thread?

Cut it out of a 300 and screw it. On? Maybe it is somebody else's fix?? Or only part of the assy.

Thanks for the diagram, its actually the same one me and the dealer parts department went over. The piece on the inside of the bumper, I think part #74 is pointing to it, is the main part that I am after. Unfortunately I think the one in the diagram looks different than the one I have. The piece that I have is a plastic triangular frame, almost the same as the 300e, the main difference is that it is not fused to the bumper but rather held in place with two rivets on the top and bottom. Can anyone verify if their rear bumper is fastened in this way as well?

I can take it apart again and snap a pic, if I can't get a handle on what part it is. But it took some effort to wire it on for the moment and I don't want to wreck it just yet! I thought about cutting out the part from the 300e, though I am worried about how brittle the plastic is and how effectively I could re-attach it to the inside of mine... but it seems like the next best option.
