It may be the bottom hinge but one of them does have a bend or twist in them. I would go look at mine to confirm which one has the twist but they are at the body man.
Also one of the hinges will have "half" a hole on the end of it. I think its the top hinge but could be wrong.
There is a great tech tip or article somewhere, about rebuilding these hinges...even has pics.
I ordered new pins, which are overzized a little, and redrilled my holes, blasted and primed them and they look great. The little horseshoe door checks will make you scratch your head a little bit till you figue them out and then you do this...
Edit: You'll notice only the top hinges have the doorchecks.
