Here's my cracked driver's side door. Working against the spring in that hinge nearly every day for 30 years took its toll. That and a few uncontrolled wind and slope enhanced swing outs.
My cousin welded up the cracks, and we ground it down smooth, but it has a serious sag between the outer two holes and the outside of the door. The metal is definitely stretched.
I now own one parts rig and another set of doors, but I'm not confident they're any better or would last any longer. Has anyone reinforced their doors here?
