I bolted it in place and used locktite. I noticed that one of the arms was bent a little, so I straightened and all seems ok.
I am not sure what caused the arm to bend. I bought this car 2 months ago and noticed that someone had previously taken the door panel off before because of the shoddy vapor barrier installation. I also cleaned and lubed the tracks which seemed to help. It now runs faster. I just hope that there wasn't anything else that I didn't see.
