can't find part name or number,,the piece is broken and I'm having a bit of a time trying to replace it,,the visible portion is the hard plastic strip about 1/4 in wide located at top of INNER door panel,,runs the length of the panel,,in the window channel,,,may be referred to as a weather seal,,2000 m/c...thanks

 

Hi `Chris,
I don't have any idea what it is or called. I hope one of our member knows & if you don't get a reply (?), I suggest calling a Chevy Parts department & see if they can help...Many times the Body Shop Manager may also know ?

Good Luck!
