When I installed CJ hardtop and full doors, I had to use all the adjustment areas: windhield, door , and tub . It takes awhile to get everything lined up......I definately had to adjust the windshield on mine to get rid of the gap between the front door frame and windshield frame.
(forgot to say...just in case...the bolts loosen on the door hinges to allow up to about 1/4 inch adjustment in all directions)
