Since the quarter-panels and the lower rockers are fixed, we want to center the door in the opening. We set the in and out adjustment first by lining the front edge of the door with the lower rocker and the A pillar. Then we moved the hinges around until we had an even gap at the rear edge and along the bottom. We needed to adjust the same hinge a few times before the door was perfect. Once the door was lined up, we tightened the bolts on the hinge to lock in the position.
