Cutout Fender flare manufacturer

[Little Pig]

I am looking for any info on cutout fender flares for '73 to '80 GM trucks (Yes, I did a search). They are not bushwacker flares. They have a place at the leading edge of the flare to mount the side marker light. Does anyone know anything about these? Below is my (admittedly shaky) rendering of these flares (left image is side-on of passenger-side flare, right image is front 3/4 view).

Edit to add: I am ultimately looking to get my hands on a pair of these. I have been looking for the name of the manufacturer so I can start asking around by name, but if anyone knows where I can get a pair of these, I can skip several steps in my master plan. I know they exist, because I had a pair on a truck I used to own (kicks self again).

I believe that the Xenon 8390's have a spot for the light, but they are not bolt on's or cut outs. Hope this gets everyone thinking. Good luck!

Thanks, AV, I had heard that these might be older Xenons. I haven't been able to find a pic of Xenon's current offerings, at least not the front ones. Xenon says they never made cutout flares though. By the way, all those black dots are rivets. I had a pair of these on a truck I used to own, and that is how they were attached.

No one's ever seen these? Oh, well, one bump then I'll let it sink forever 'neath the waves...
