Hood and Door Hinges on a Duster

Couple questions. If I release the springs for the hood hinges is there a tool or video on how to get them re-wind up to install them?

Door hinges. I expected that I would need to rebuild the hinges since on a B-Body they are always wore out. Neither the Duster nor the Dart parts car seem to have any play in the door hinges. It it normal for the A-Bodies not to have wore out hinge pins since the door are no where near as heave as the B-Bodies?
