Search the forum for SX-R build thread, in that thread he shows how he does exactly what you're asking how to do and describes what he uses to do it.
Thx for your input Koup SXR, however as I said, the dealer has done this:The front plate is screwed into the center black bumper insert. You'll need to remove the license plate screws and you'll see how it’s screwed to the bumper.
No wonder... LOL^^^The dealership seen what you started and said "Piss on these guys...they want to relocate their plates. Well they will have to buy our parts to be able to do this...." LOL
