I'm in the process of installing a headliner in my 70 Dart so I'm removing the interior. How do I remove the long black metal trim pieces that run from the top of the A-pillar all the way back to the bottom rear corner of the rear side glass? This is on the interior of the car, not the chrome piece that runs along the drip rail. I have the screw at the front and all the surrounding trim removed but it still doesn't want to come out. I'm worried about bending it out of shape. Any suggestions?
