actually ive seen the ones the bolt up from the bottom, they have frames for that type of install, and if you dont want it you can take it down and not have to see the bolts, i might go with that

 

you will have to drill holes in the bumper cover to use the factory plate bracket.
HUGE holes, as the bracket is held in place by large rubber expanding crush-nuts.

 

ill probably just get the undermounting bracket, i saw one at advanced auto parts

 

you can always just take a hammer to the liscence plate, completely f***ing it up, and keep it in your trunk. if you get pulled over tell the cop your dad backed into you and you just fixed the bumper and were gonna put the plate on that night
