is the fact that the crimped hinge is rusted through in a couple of places. So the metal is thin and could easily seize up again at any time. Which, considering the box must be removed to fix, I would rather not have happen. Nonetheless, I could do some surgery. But it would not be up to my standards. Given all the likely donors out there in better shape, I would prefer to start a bit fresher. I should mention that I had to put the hinge bar in a vise and use liberal amounts of Liquid Wrench to get it freed up. The design is such that water will get in that hinge again.
