Zip tied?
lol yeah -.- kinda ghetto, but the self tapping screws wouldnt stay put.
i'll put rivets in it when i have time, but until then it stays pretty well.
i have two self tapping screws on each of the corners, and then two holes at the top of the lip where its zip tied to the bumper its siting on.
the fit wasnt perfect, i have about a 1/4 inch crack on one of the ends cause thats the only way i could get it on the bumper, but it doesnt seem like it will be spreading anytime soon! *knocks on wood*
