cobra front bumper help...

so i finally have the last part of the cobra bumper puzzle. just got the bottom lip spoiler for the bumper, but no fasteners.:notnice: i went to ford parts dept. and they were not helpful at all, did not have the correct fasteners, and could not get them for a while. what should i use? anyone have some #s on these clips, i believe there are 2 different types, and i have an auto store here that sells tons of those retaining clips, rivets, etc...but i need some info on them...anything would help, thanks in advance.
 
I think the factory uses some type of push pin, try Advanced Auto and look in the "HELP" brand for some of them. The bad part about the push pins is that they come loose, the good thing about push pins is that they come loose when you bounce off the parking curb, thereby leaving the nose intact.
