Or if you want to get fancy you make the spacer out of 1/2" MDF and cut to the same profile as the grille, though that makes finishing complicated and it's a bit delicate in process.

Actually, I can think of a rather elegant way to do it with (lots of) neo mags. Like a bit holder on a socket driver, an alignment pin or three makes the grille and even the ring the grille is attached to fit into place securely, and then a bunch of large neo magnets hold it in place during normal loads and even small car accidents...
