What is this part?

I have a 87’ cabrio and trying to figure out what this part does or covers? (I tried searching, but not sure what to even search for, so thank you for help!)

A picture would help.

Thank you! Haven’t heard or seen that before. I guess it will be worth keeping.

Yes, definitely worth keeping. Let me know if you decided to sell it. 😀
