It's interesting that you mention possible collision damage because I know that my driver door is not original to the car. I can still see the red paint in places.
If you look at the first picture, you can tell the striker was literally ripped out. The two sheet metal screws you see were holding the cage for the nut in place. The quarter panel behind the door had about 40 holes where they had pulled the metal back out with a dent puller. The rocker had a section with about 25 puller holes, brazed metal repair and 1/4" of bondo. Sam cut that section of the rocker out and replaced it with a donor piece.
