Front rubber flap
 

Hi

I’m not sure what you would call this, but the black rubber piece that sits in the front under the body seems to have pulled half way out. I see where the tabs insert and some are still in place. It doesn’t look like the rubber strip ripped, but pulled out of where it inserted. I can’t figure out how to push this back? I can’t find a description of it’s insertion/placement. Any thoughts or ideas?

Welcome to the forum. You might stop by a Chevrolet body shop and ask them. It may require removal of something in order to reinsert the tabs but I'm not sure not having seen it.
