So far, Zombie's idea seems the best. The only problem is that I had to install a bunch of felt in the "forks" of the frame to prevent it from chaffing the black plastic grill webbing.
I should have Round 1 of my custom bracket on Monday. It does use adhesive, but it is non-permanent (meaning it will not destroy your paint). Stay tuned for a write-up late Monday or Tuesday. Round 2 (the colored part) should follow shortly thereafter.
Also got my personalized plate reserved today.
