I am missing these from both roadsters, there is one at each side of the trunk opening near the top, they hold the carpet in place. There is an auto paint supply near me that has a huge selection of clips and fasteners but not these. I will hunt for them but I don’t know what I am hunting for. Anybody know if they have a name?

 

That is actually for the cargo net.
What cargo net, you say? Good question.
Not sure any Crossfires came with one.

 

Just went out and checked the cargo net fasteners on my wife's Hyundai Sonata to see if they would fit.
When I started unscrewing the first one it certainly seemed like it was going to work. Problem was
the screw was coming out with the clip.
It's male and you need female.
Willing to bet that you could make any cargo net clip with female threads work.
