door adjustment

I have a '67 dart. My driver door is slightly too low in the rear, but otherwise gaps are good, lines are good. I just want to raise the rear of the door upward a few mm, not in or out. Do I loosen the top hinge only to adjust this, and if so, pillar or door half? I don't want to loosen any bolts I don't have to, it is a minor adjustment, but important as the door is too low at the back end. Passenger door is perfect. These are new hinges, got the car painted recently, just need this last adjustment.

Thanks all.
