The plastic piece in the back of my car won't stay in place,WTF!!! I noticed the passenger side has these plastic screws in them. The driver side doesn't even have holes cut where a screw could go in. Only thing I can figure is it's like that due to it being a interceptor in it's past life.

 

Just in the very back? Mine does that after looking for the remote CD wiring...there's a fastner there...stripped mine pulling it out.

 

On the drivers side, there are trim/panel fasteners, dont know if thats the correct term, basically they are screws with ridges running along the length to hold the panel on. They can be kind of a pain to get on though. I bought a pack of 15 at O'Reillys. They are very usefull, especialy if you ever take you interior apart. I dont know why they didnt use those screw type fasteners that are on the passenger side, on the drivers side too.
