I wouldn't epoxy/glue the plugs in. So Cal cops will site you sooner or later for no front plate . In some states its probably not a big deal, but here they are anal about messing with modded cars.

Its not as nice as without it, but I mounted it with a backyard special liscence plate bracket and Mugen fasteners (angles the front plate) Turned my front plate into a Mod

 

goddamn it this shit just happened to me, the whole screw assembly fell in, ugh, now i gotta take off the bumper!!! u guys think that little piece will fall out eventually? or will it be stuck in there and rattle forever

 

You can pop off/on the front bumper in 1 hour being smooth. You have to take it off.
Same thing happend to me too.
