VHB tape.
The front license plate frame on my new car came un-attached (some states don't require it, and apparently some don't like the look of it, so it's user-install optional), and to attach it, it was just provided with 2 strips of VHB tape.
Thanks for the feedback. I think I'm overthinking this a bit. I found out it's legal to drill holes in the plate as long as you don't obstruct the numbers. The truck is a wood hauler so sees some rough territory at times. Thanks again.
