11 One of the harder pieces to remove is the door jam area. It's tempting to leave this in place and make the new quarter fit to it. Don't do it. Take the time and do it right. The extra time spent here will be saved when you have to do the bodywork down the line. Besides, more seams means more places for cracks and failures over time. The first thing you'll want to do is find all the factory pinch welds. Several of them are located around the area of the door striker.
