I need a good used headlamp socket, with good connectors (if possible) for my '70 CB750K (and used on many years, I believe). NLA from Honda, and have heard from a reliable source that many aftermarket suppliers are NLA, as well. One supplier claims to have it for about $8.00, plus (get this) $14.00 shipping! The ones from a typical auto parts store have all three wires black. I've attached a photo of the one needed. Thanks in advance!
