im pretty sure its riveted in...from what i understand u can drill teh rivets out but i tried that and broke a drill bit...so i dunno, im interested hearing the answer as well
i never had that front plate bracket on my splash... then when i repainted my bumper.. i decided to weld those holes shut which loos a lil better but then once i went to put the bumper billet grille in.. it was made to use those holes to mount so i had to modify it to fit... no biggie... it worked anyways... front license plates SUCK!!!
all i'm sayin is, i bought my truck from my dad, and it had bolts in it. i asked him if he put them in there and he said, "why the hell would i waste time doing that? sounds like something you'd do."
