1966 Dart door gap issue, rubbing.
Def start with the hinges. If the pin and bushing work you've done still require you to lift the door to close it or there is play in the hinges, you need to address that before moving on to the fender adjustment.
I'm not 100% sure what all needs to be loosened on a 66 but on my 72, there are two bolts down at the rocker, one on the side edge of the cowl behind the splash shield, 4-6 bolts along the top of the inner fender and two at the hood support
