Thanks again Caspian and Ron. That picture makes more sense. Not really sure why they were really used?? I did not replace these on my 66' and have not had any issues, thou I did reuse the nylon washer so not to mess up the door panel. Guess the keep tension against the handles so they don't feel loose? I will get some pics of my originals tonight, hopefully this will help others searching this topic. And by the way, the two "heavier, stiffer" springs that I too believe go on the window crank are painted black while the two "less stiff" springs have surface rust... These are original to the car as the door panels looked to have never been off.
