While restoring our 1960 F100 it came time to install the internal parts of the doors. As an assembly aid we took this door and removed the outer skin to reveal the inner workings of the window regulator, locks etc. This helped us to determine what should be installed first and how to assemble correctly. Maybe these pictures can help when your time comes to rebuild your doors. See all the pictures below. Click on pictures to enlarge.
