For the parts with the Fogs, it is a pain in the ass, but it can be done, your gonna have to remove the fogs first... then you need to unscrew the plastic panel on the underside of the bumper in front of the wheels... that will give you access to these panels to push the tabs thru to the front...
It don't look right, so don't take them out, but if your gonna paint them, paint them and put them back...
I am actually wanting to do the center grille nostril delete thing, and then fiberglass or whatever the side grilles and paint it to match the bumper that way the only grilles I have are the ones for the radiator...
