Allen:
Recall that old Beatles song "Let It Be?"
If the doors work well, seams line up, nothing rubs, clunk shut nicely, I would consider letting it be for now. Live with it a while. Let it set out in the sun and see if expansion of the panels changes anything. With time it may become less of an issue.
I would also guess that if the numbers are applied, and if the extend below the bottom door seam, and if the are perfectly lined up, it will divert the eye's attention to the number and not the circle, making the minor imperfection noticeable only to those that have read this thread.
I spent many hours getting the door adjusted on my GT. The slightest movement at the hinge can have significant ramifications at the other end. As Randy noted, make sure you are well rested and have lots of time if you decide to tackle the task.
I suspect that RCR used nuts and bolts to secure the hinge to the body. To gain access to the nuts on the rear may require remving the gas tank filler cap and filler hose. You can then reach down through the gas cap opening to access the nuts on the back side while loosening the bolts on the hinge side. Loosen just enough that it can be levereged, then carefully move the door forward, backward, up or down from the latch end until you are satisfied with the alignment.
Problem is once the roundel lines up perfectly the seams may be off.
Just my ten cents worth . . . . .
Every adjustment affects the door in multiple plains..
