My headlight issue is approaching a finale. While under the passenger's side dash looking for the proper relay (pre-L location) I found that the relay panel is secured by two wing nuts and can be dropped down for better access (a discovery for me). Protruding down from that panel is a long(4 or 5 inches)threaded rod also with a wing nut but it does not secure anything .. it's just there. Question: is there suppose to be a panel or kick plate that that long rod secures? What is it's purpose. I've owned 3518 since Jan. 1973 and have never removed anything down there (that I can recall .. but I'm older).
