Missing plastic cover screws help!

Hey guys, I've after loosing all the screws from the front plastic covers on my 91 civic, I removed them and when i went to get them again they were all gone! I think they are all plastic but cant remember, some of them look like plastic bolts and others are plastic screws.
I'm missing them from the wheel arch covers, the 2 plastic parts which go under the front of the engine (right below the radiator to the sides) and from the parts which kind of goes around one of the arms on either side. If anyone could list the number i need of each type for each part and where they go like bolts or screws I would great appreciate it!

Get them from your local junk yard... chances are, they won't even charge you for them, just take a few plastic baggies with you, so you can remember which ones go where.

(Thanks for reminding me, I still have to get all those plastic pieces lol)
