i have a "similar" lamp, as it is "close" to the first picture, as in it has a plastic body, and a "similar"[ly] shaped metal mounting bracket.
where it differs is, it has a female bullet plug, and comes with a white, three socket, flat female plug connector.
the lamp pn is : 4240300, and that translates [i think] into a cordoba or mirada piece, as well as several K car years.
i'm just throwing this out there. don't know if this helps in any way or not...........
