Front license plates
 

I recently brought my 94 S420 into a state which requires front license plates. I don't have a front license plate bracket either installed on the bumper or laying around.

I really don't want to screw anything into the bumper (but if I must, I must)

Are there any creative fixes that people have come up with to install a front license plate onto the bumper area that does not necessitate the use of screws?

alternatively, if I must screw, do I need to worry about hitting anything behind the bumper?

thanks all!

If you don't mind, you can always put it on the dash on the right hand corner when you park the car. I doubt they'd pull you over for it unless you were breaking another law.
I do it in my wagon because I don't like the look. I just keep it in the door sleeve when not in use.
