There is a thread on evom called "the official part number thread" or something like that. Search on there and you will find posts by me talking with another member and this member gives me all of the part numbers for the hardware under the headlight. Again, I feel you only need the black plastic square clips. I ordered everything and didnt need anything but those. I ordered them from the dealer. Took about two days and $3. Now it looks good as new! A pic as proof!



I probably had my front bumper on and off 10 times and it alwasy went back in fine. Then I put on the lip which made the whole thing more rigid and harder to line up. So I cranked a little too hard on the scews hoping it would pull things together and instead stripped out my black plastic clips and I had about 1/4" of gap on each side. Now as you can see it looks sweet.

 

PS: Had the same issue. If you can wiggle the thing around it needs replaced. Those things should be in there solid. You will see when you snap the new ones in how tight they should be.
