I dont have any pics but the way I secured the mesh was with small nuts/bolts/washers through the bottom lip.
Then the top is screwed into the white 5mph bumper with washers.
Then on the ends where the fog's go, small bolt through side.
I had silver mesh for a while, now its all black. All hardware painted black to match mesh, nothing looks out of the ordinary, besides my own aftermarket foglights.
One other thing is to cut away all the tabs from the old grill on the bumper itself.
Dremel could be used to trim excess bolt showing through bottom lip, but you would never see it anyway.
