That looks like a pre-facelift (90-91) front bumper. Does anyone know if the part numbers are stamped on the lights anywhere? I have a set sitting loose I can check.
On that note, how are people mounting them in the RC/CS bumper? I see a couple tabs that look like they're intended to hold something like fog lights in those pockets but I can't see any way to actually get a screw in there with the light in place and it seems like it would be pretty bouncy/prone to failure compared to the big metal brackets off the donor car.
