Larry,
I have been building the door surround to match the window frame. I had to remove some serious material around the left window to door area. I have the old drip edge, held against body and keep opening and closing and then grinding fiberglass until a good fit is obtained. Left side appears to be close or done (I don't think this is ever done). The left door could use more fiberglass reinforcement inside, against the latch assembly. I also had to add fiberglass to the inside of the door jamb latch area, to allow for grinding to get a decent fit of the latch to striker assemblies. Starting on the right side door to window fit this week. I had fiberglassed inside the car, around the door window area to allow the outside to be ground to fit (clearancing for window frames). Thanks to your advice, I did not glass on the inside of body window area. Did not want to take up interior space. Since adding material to the door surround, the roof structure is more solid. And so it will continue.
