1970 duster passenger door sag

hey, I got the door close to where I want it but I noticed that the door is poking out towards the back of the door "not flush with the body" is that able to be adjusted? or is my door trash and I should just get a new one? id much rather repair it but if its gonna be more trouble them its worth I might aswell buy another one.
need pictures. can't really give any advice without seeing which way you need to go or what you have going on.
