4runner bumper help

[dragginmits]

well after almost a year i think ive finally got the mits runnin and reliable so im trying t wrap up the loose ends on the runner bumper swap purchased some clear turn signal lights to mount in it but since my bumper was purchased new i dont have the mounting hard ware for them appears to just be a sheet metal screw with a clip that snaps into the square holes in the bumper anybody know what this clip is called and what size i need. ive tried to get it at a salvage yard but they just crumble when you remove them
