Found the source of my trunk leak...but need a solution!!! (Gas door stopper)

[audiquattrot]

So I've been trying to track down a leak underneath my battery tray...replaced my c-pillar trim gaskets + taillight gaskets....but it still leaked a little after that.

Took a hose to it, and realized it was coming from below.

I had my car painted a couple months ago, and they forgot to put this gas door stopper in (held in by two screws). I sourced the missing piece from my friends' donor car that we scrapped. Problem is, the screws don't have a female nut in the body of the car to hold them in. So it slides right in w/o having to screw.

Question is, what am i missing?? I tried to look on the back side (inside the trunk) and can't gain enough vision to see whats missing. Gaskets? bracket inside the trunk?

Any possible solutions you guys recommend? I was thinking of siliconing the holes for now, but the problem with that is, the pin lock would still allow water to get into the trunk since there's a gap around the pin. I'm also contemplating (if there is a way), to disable the gas door pin from locking...and siliconing around that as well.

HELP! LOL

would be great if someone can unscrew theirs for me, to see if they can see anything.

am i missing #25? I'm trying to figure if #24 is the gas door pin....b/c if so #24 & #25 part numbers are no longer available.
