How to square up door hinge screw mounts?

[72farmer]

I have a drivers side door on a 71 that is hard to shut.I have all of the guts out of it so I am trying to make it better by adjusting it.I have the door off.And when you lay a straight edge across from top to bottom hinge mounting locations the bottom or top (not sure which one) is not square to the other.I don't see any cracks around hinge areas.
I watched a utube of a guy that squared the hinge mounts up by bolting a plate on hinge mount location.(ThisOldGarage)Then took a hammer and straightened out hinge mount location.Can I do this to square up hinge mount?

Could you shim the upper bolts to bring it closer?

Is the floor that the vehicle is on level? if the vehicle is on a perfectly level floor. is the air pressure in the tires, as well as tire tread the same ? if that is good is the springs sitting in the same place i.e. ride height front to back side to side. My point is that I'm not sure your what your trying to achieve with the level? I know if your setting a door in your house a level is required but not for a vehicle. to properly adjust a door you want to set the gap evenly along the bottom or rocker panel and then adj the door to the cab corner both should have a even gap. on a truck its to the best you can get it then you set your fender.
If your door is stiff to open and close it may need pins and pushings installed

Yeah just using level for a straight edge.
