Hello! I just recently purchased my very first car on my own, a 1989 Camaro RS (standard model for this year I believe), and was looking around my car when I found a hole in this triangle shaped piece next to the driver side MANUAL mirror, please, what the hell is this called? I can't find any replacement pieces for it online and any help would be much appreciated! The piece I am referring to is shown in the this photo by a black arrow, it's the black triangle piece.




The black triangle at the top of door.

Thank you!

 

Could this be it?

 

Its typically called "triangle seal".See em all over ebay, used/new.Maybe classic Ind, idk.
