The bracket and housing are the same as an E body but the end plug connector is not. It also works like an E body's (mercury switch). The pictured one has already been modified with correct connectors and is in my '70 Barracuda. Thanks.

The "viewers" seemed to be as stumped as me. Plug looks like 76-77 Volare but not the rest of it.

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...........
