I have a 1952 3600. I ordered and received new door relays for both doors because the splines on the shaft are worn and the handle will spin freely on the shaft (I have to open the door using the outside handle now). The new ones look the same as the originals. The problem is one of the three screws holding the mechanism onto the inner door panel is covered up by the pivot for the relay arm (see the attached image). How do I remove this screw?
