My 302S grille is ready to mount - anyone have an easy way to remove the stock grille without removing bumper, etc? I'm sure I'm not seeing the obvious (or hope !) - I removed the four pop-out plastic rivets as well as the screw/washer assemblies just at the inside of each headlight. The grille assembly is looser now but not loose enought for me to get at the tabs that hold in the grille.
