Re: a pillar trim -there isn't any unless you're talking about the interior-bead looking thing along the edge of the door opening. Since I'm new to a-bodies, let me know if I'm on the same page as you regarding this.
There is plastic trim on the inside windshield post that runs from the dash to up to the roof. I think what you are talking about is the weatherstrip that is bonded to the part that attaches to the pinch weld.
