Black vent inside door jamb

So The screw that goes in the bottom hole fell out years ago and I just got around to get another one. But when I went to screw it in the plastic inside the hole that the screw threads into is not there anymore. Does anyone know where that plastic piece can be found?

Have you tried your local Mitsubishi dealer?

Yeah they dont carry parts for my car anymore. They say “nope car is too old” but I dont know what that tiny plastic piece is that is inside the body of the car. The screw has nothing to screw into. Idk the name of the vent either because i cant find anything online on it.

Here is actually a pic of the plastic piece. I cant find anyone that has it. I checked my passenger side, removed the vent and the white plastic pieces on the passenger side were all crushed as well

You should be able to get some plastic inserts from your hardware store that fit into there to replace your current ones with…

Oh ok ill try that then
