Look at part# 11547637

UNDERBODY REAR AIR DEFLECTOR(PART OF 1)(NUT-HEXFLNGE,T5,20 OUTSIDE DIAMETER,10 SOCKET, PLASTIC)

I'm not saying that's it, but it's the best I could do.

I'm hillarious. When changing my fuel filter the other day the screw broke off in the plastic nut for the lower covers and I had to throw it away. While looking online to find what the part# is I find someone who already did the hard work.

I ordered a bag of these, and they have worked as replacements as the original nuts progressively strip out after 8.5 years and almost 200k of fuel filter and emissions sensor replacements.

You live in the rust belt?

Mine haven't stripped but the screw that's on the one on the fuel tank strap broke off. I can buy just the strap for like $28 from rock auto but not sure if it's worth it. I may never change the fuel filter again on this if I sell it.
