I opened the rear barn doors on my '51 Panel to see how I could adjust them so the doors don't touch in the middle and the left one stops on the striker and not some random spot where the frame touches the door on the left enough to keep the door open about 1/2 inch without slamming it.
I started loosening the top body-side hinge bolts on the passenger barn door to see if there was any adjustment there but had to stop at 2 bolts because the wife came out and I'm technically not allowed to work on my truck until I finish some stuff in the house.
