I have a 92 firebird and some idiot decided to kick/hit my door or something so now I have a giant hole at the bottom of the door... It's the plastic part at the bottom... What is that called so I can start looking for a new one?

 

The only plastic pieces I know of are the ground effects themselves.

 

Sounds like the door ground effects piece...look similar to the pic below? I just got a passenger side one yesterday. I believe members Coult_91, tpi-hearse, and/or Bull may have this piece, shoot them a pm.

 

That's it! thanks, I'll pm them and see if they have some.
