Since the photos are missing in the first post I will share mine from today's grill swap.
Before
AFTER
Here is the tab situation, just move the block for the screw from the inside tab to the outside tab.
You can either cut the inner tabs off, but you will never be able to switch back to the newer grill, or you can notch the back of the older grill.
Last step is to drill a new hole for the bottom, middle screw.
My valance is a bit beat-up from the bumper being pushed into it from an accident so I plan to replace it with an older valance in the future that will eliminate the gap left at the bottom.
