Door too low on striker

My 67 Dart convertible drivers door has the same issue. with the door fully open there is no significant play in the hinges. with the door almost shut there is enough play to account for the sag and i can lift the door up and make it shut perfectly.

My bet is the lower hinge / pin is warn. I thought about using a repair kit but they require drilling the hinge out and inserting a bushing. (I don't like the repair kits) Or buy a replacement hinge set from AMD or the like.

You might be able to shim the lower hinge between the hinge and the door which would raise the handle end of the door.

Good luck
