I think the "sag" is caused by whoever is getting out of the car, is pushing down on the door to get themselves stood up. Myself I push down on the rocker panel to stand up. No chance of damaging the door, IMOThe doors on my 69 gt are really bad too. They sag a lot and they are hard to close since I put new door weatherstripping. When the car is jacked up right behind the front wheels the doors shut perfectly! But that is a problem in the future.
