Licence plates

[kingsandman]

just use a slightly longer bolt and double nut it. tighten the first nut and jam another nut against it.

My suggestion:
Use a Torx AND a 12-point--takes two tools, so takes longer to remove. (Make sure they are cross-threaded---I can help you with that--and put really good glue on the threads!)
In addition to the TORX and 12-point, use baling wire to weave and wind a complex pattern that also holds the plate in place, in case youryour first level of attachment be breached. When finished, be sure to cut the ends of the wire in a barb-like point, to the best of your ability. (There are books on Celtic Knots and designs, if you want your vehicle to look less redneck like.)
Hope this helps.

LMAOOOO...!!!! You're nucking futs, PM!!

Ditch the license plate holder and just super glue the plate directly to the vehicle.

Do you think the little buggers will have a bottle of nail polish remover with them????

Saw a guy yesterday who had his license plate surrounded by about 4 rows of barbed wire.....a bit redneckish but I guess it might work!
