I decided to remove the front bumper to clean the radiators. At the same time I’m installing DIY grill screens.

side screens are complete. I want to also install a screen in the center section (no 3rd radiator - manual trans). I’d like remove the center “wall” (pic below - taken from the back side of bumper) to assist with a cleaner install and then put it back together. Clips on top are simple enough but the bottom won’t let lose and I can’t really see what’s going on below. Does anyone have experience removing this piece?

thanks for any input!
