Hello from the Catskills. I am the new caretaker of a 1974
ECO Featherlite that I am going to restore

. Last owner wanted to make a tree stand out of it!

. Looking at the door hinges, a fiber bushing must be missing? Door seams to sit low. There is a bronze ball bushing the bolt goes through. Are the hinges just worn out? Any suggestions on a home repair.
