i have been doing work under the hood and realized that some of the black screw things that hold piece down are missing. like the ones that hold the engine cover down, the ones that hold the piece over the lights down, and i think the strut cover ones. where can i get these, does autozone have them, and whats the right way to take them off. i wind myself breaking them when i try. sorry for posting so many this weekend.

You push the center in to remove.

I believe those particular ones are a dealer item, parts stores may have something similar though.

If you want to be able to remove the engine cover without having to use any effort at all..........go to your local FLM dealership with one of your clips in hand and tell them you need a few. I think they are around 1.50 a piece. Personally, I think they're worth it because you don't have to pry on them to remove them or pull on the engine cover to pop them loose from the mounting bracket holes (all which could damage your cover).

It took two dealers to get the right part.
