Had a question I hope I can get an answer for concerning the dome light wiring set up. I noted the dome light was grounded to the cab of the truck via the frame of the dome light. The new harness I have has a separate wire for power and ground. Looking at the way this dome light is set up I am not sure I need two wires, but I would like to change the current set up (no pun intended) because the wire going into the socket for the bulb is really worn. I did some searching on the web and found some dome lights on the Filling station site but the size they give for the lights make them too large for my use. 1953 3100. Any suggestions?
