Door sags and will not shut?

That car uses a captive pin set up, so you replace the complete hinge assembly. For that you get the replacement hinges. Outline the position of the hinges on the door and on the pillar. Then support the door and remove the bolts that hold the hinges to the door. Now gently let the door sag just enough that you can remove the bolts and nuts that hold the hinges to the pillar. Remove the hinges. Line up the new parts with the marks and install it. Tighten the fasteners to 20 ft lb. Now carefully close the door and check the alignment. If it's okay, then you are done. If not, then you need to use the bolts to adjust the alignment.
