Last winter I bought new door panels, since the originals were crumbling. I took the mounting clips from the old panels, attached them to the new panels, and mounted the panels to the insides of the doors. Then I was able to re-install the window crank handles and some door latch trim. The new panels look nice and fit properly. I also put the front floorwell carpet pieces back where they belong. Now the interior is 100% re-assembled, and better-looking than before!
