i need help i cant seem to figure out how the retaining clips hold the ls sport lip on my 2002 z24.  If someone could explain how they work that would be great.  I looked at gm parts direct for like a parts schematic and didnt find what i needed.

their clips.  i believe its like a pressure clip.  theres slots in the bumper and the clips that are part of the lip are a tad bigger than the slots.  so when you push the lip up the clips get moved in a little til it passes the bump out on the clip and it snaps into place.  its hard to explain without a picture
 
 
i figured it out.... them clips are a pain in the major butt to get to snap in but all in all my car is lookin good.  the lip has a few scratches in it but nothin i cant live with.
