need a little help

this pains me to say this, short story shorter, the deck lid lip got knocked of my 07 Type S :(. i know i have to take the inner deck lid liner out to see what is there, but at -20, i don t much feel like it right now. the lip looks ok, it appears to me that there is plastic screws with double hear or along that line that hold it in place, it looks like one slides the plastic screw onto the spoiler and slides it throught the holes in the lid and tighten. All the holes are ok except one that broke away, which should be ok. i am trying to find these plastic screws or whatever they may be called or at least a part number, to no avail, for me anyway. it looks like 6 or 7 holes, but two have metal tabs on them, am sure this is to help stabilize the lip, and then there are two, i believe that have green inserts in the lid, but go nowhere, or have nothing protruding out of them and and kind of a tri angle shape. anyone with any help, i would appreciate it.

thanks al
