I usually have a good answer on COE questions, but a problem like this taught me not to remove COE doors, if I didn't have too. I've owned over 25 COE's through the years, & removed the doors on at least four of them. Had one heck of a time getting them lined up properly, on everyone of them. I finally noticed that just tightening the doors snug, then closing them, & adjusting the gaps, as needed, then with a helper, or two, try to open them, without moving them much, so you can get your final torque, on the hinge bolts. Good hinges, are definitely, a must.
