Hi Wendell,
Attached are two pictures of the paint edge from my 67 w/standard interior. You can clearly see the rear paint edge line. The front edge is hidden under the rubber, which is very brittle, so I didn't want to pop out the black plugs. Also, there looks to be traces of adhesive in that area so I didn't want to risk tearing the original rubber.
The picture MooneyDrive posted displays an excellent view of the bottom paint line under the door panel.
MooneyDriver, can you get a front shot of the paint edge under the rubber on that door?
Mike
