Chasz, you solved one mystery for us in that the The Filling Station has not properly identified their product and they span at least 1937 and 1938 for trucks. Here is a link to the female part of the connector that goes from the light sockets in the reflector to the body of the head lamp. It even includes the socket contacts which is fantastic.

If you look elsewhere in their catalog you find the male part of the connector with metal conduit. When wiring my truck I would have died and gone to heaven to find those parts but I guess I kept searching for "1937". Thank you!
