Adjusting doors

When I had my 71 Scamp apart for paint I inspected my door hinges and pins. I ended up replacing the pins and then aligned my doors, which shut nice. That was 2 years ago. I've noticed this past summer that the drivers door sags just enough that the door doesnt shut correctly. Unless I pull the door hard to get it to ride up on the door striker. Once shut the alignment and gaps are nice.

I've checked the hinge pins and they are still in place as well as the bushings. Im not sure where it moved but Im guessing it is where the hinge meets the body. Is it possible to adjust the doors with out pulling the front fender off? Any suggestions would be appreciated
