To adjust the front of the door in or out, you need to bend the hinge. Somewhere on this site there is a writeup about that. Normally you have to do it with the hinge removed. I bent mine before the truck was painted using heat. Bending the hinge out at the big bend will cause the door to move in.
Now I remember. One of our members Chuck the Truck has an explanation on his website. Here I found it:
