The buckets for the headlights on my 1937 Chevrolet SD have 3 pin bayonet connectors to the truck's wiring harness, see attached photos. I can't find these connectors shown in the parts book, and I haven't seen them online at the old Chevy parts places. Has anyone found a source for these connectors?

Thanks,

Jim
