I just copied the grille straight off the LC500, because I have no imagination. A third of the price of an OEM replacement, 100% less ugly chrome, and like half the weight for ultimate weight reduction and style. 
 
The Grille is printed in 4 pieces and is shipped unassembled. All stainless hardware is included for both assembly and mounting. If you can't figure out how to put it together ask your uncle or just smack with your purse.
