I was starting to think the same- move on for now. You are right, the quarter is rusted out where it meets the rocker. This area was packed full of mud and fiber glass.
I'm not sure I'm following you on the sentence about creating more in and out movement on the hinge.
Another troubling thing that may just be the nature of these skins is that the gap with the quarter doesn't vary linearly. It doesn't start narrow and increase in width or vise Versa. It might start big, get small in the middle of the door, and then get bigger at the bottom. This tells me that if my aftermarket AMD quarter is the same I may have to add metal in places to keep the gaps the same.
