How do you get those little plastic screws to come out without damaging them? Mine won't budge.

In the fender wells?? They turn about 1/2 turn and then pull out the center section.

If they are full of dirt they are difficult to get out. WD-40 or even water may help.

If you break them they are about a buck each to buy new ones

The screw is in two parts, a center and an outer.

If it gets dirty like the above has stated, you can use wd-40 or do what i did.

Hold the outer side of the screw and turn the inside with the screwdriver. Usually this would cause the center to twist and pop out a little like it should. Make sure your only holding the outer side of the screw.

If this does not work used the wd-40 :)

get a philips screw driver and turn slightly to the left. you will see it come out. if it's stuck for some reason you'll have to loosen it by popping it out a lil while you turn.
