Who made/makes this C3 Corvette fixed headlight conversion in the grill

?

Probably homemade. Doesn't look like it would really take a kit to accomplish that.

well I don't know if it is a kit or a DIY but I've seen at least 4 over the years. As far back as 1981. All I have seen have a chrome bezel/surround for the lights so it is either a kit or repurposed lighting from another car model. Any know any details.

The headlights in the first pic scream "80s-era GM Sedan" to me. Perhaps the lights and surround came off of something like a Caprice. I wonder about the front clip though. Is it a new piece without headlight doors, or did they shave the doors and smooth it over themselves?
