I found once i had the door on the car and lined up that a few adjustmentst had to be made to the door support and the rear door jamb. I found that the rocker must have sprung back a little bit from the factory and to make the propper door gap the entire top side of the rocker should be lined up and welded before the bottom. If I clamped both top and bottom of the rocker on, the bottom door gap was about an inch wide and where the a pillar and the rear door jamb stick out was too far away to be welded.
