The cabin door on my J has about a 1/4 inch gap at the top when the door is closed but not latched. This makes it take a fair amount of extra force to latch as the clamshell at the top latch has to spring the door top inward before the mechanism goes over center. The service manual says, "NOTE Door contour can be altered slightly to conform with cabin contour, if needed, for proper fit and sealing." Has @M20Doc or anyone else done this? Any tips on how to do it.? The door is pretty stiff. T
