Here is where the broken welds need repaired, to keep the door straight, and where I have flexed it back to.

I hope this helps someone else with a similar issue!
From what my family knows, and what I know, the door has never been abused, hit hard, slammed excessively hard, and no accidents involving it. The only issues were bad hinge pins.
I am thrilled that this worked, as I have a great rust free door on the car, and finding any things Pinto part related is a challenge these days.
NOTE: I replaced the door hinge pins prior to attempting any body line matching or door straightening, to ensure correct door height and geometry with the hinges. The fender was also removed and manipulated as much as possible to ensure the door was the issue and not the fender itself, or the quarter panel. Manipulation of the door by force, like I used, should be used as a last resort.
