Part help please

[Wizness]

So I've been looking for this part but can't find it on any parts breakdown and even went to the dealer and they apparently can't find them on their diagrams as well. I'm looking for the little plastic nuts that hold the rear bulkhead down in a 2006 Coupe. I am missing one so I looked at the other one I have it looks like it has a part number on the bottom of it but I can't read it as it seems to be worn off a little. If anybody could help it would be awesome. Thanks a lot.
