on my 54 laurentian under the hood up by the headlights there is a junction block where the wires come out of the engine bay and join to a electrical block then the wire s go from there to the headlights and signal lights.Not sure of the official name,junction block,wiring block?Anyways my passenger side one decided to break the other day and now no ground so ps headlight has decided not to work.The blocks are riveted to the top of the rad support.Anyone know of a supplier?I thought I had spotted some on ebay a few weeks back but of course cannot find them now.
