Both doors, driver and passenger, on my '73 Charger seem to bow out at about the mid point in the door, more so on the driver than passenger. The passenger door sticks out at the bottom. Thought it might be hinge sag but the top's of the door seem to line up well with the body. Don't think there was previous body damage but don't know for certain. If there is any bondo from an accident it must be very thin because my magnet can't tell a difference. Any ideas?
