There is tons of room in these housings. If someone were to have no life like me and want to waste hours and a few hundred $$ to reproduce this, they may want to think about adding some small fogs inside the housing with the 90mm highs and lows. I'm not bothering, personally and am foregoing the ability to retrofit it later as I will be mounting the lights far apart for aesthetic reasons. Even if someone were to try this same thing as me it wouldn't look the same as there are different depths and relationships between the lights spacially that someone could try.
Fitting these completed housings in the car is going to be the harder part. I don't think I can escape using a sawzall for some of the little supprts behind the stock headlight housings. Also, the charcoal canister and colant overflow tank may have to be moved a little bit to clear the rather deep high beams (BFD). edit - this won't be an issue as I mixed up the high and low beams -
This is a hollowed out housing with the basic brackets set up. Simple angle alloy cut according to a template I made.

Headlights installed. The housing will be more filled in with haxagonal perforated metal (also being used in the new grille) will fill in the front around the lights


Still need to finish polishing the lenses.
I could make templates of the basic set up and someone could replicate this pretty easily. The hard part and super PITA is clearing the lenses out, but some pretty cool results could be had with alternative ideas (like no lenses, hole sawing them, flush metal or fiberglass surround approximating the shape of the lenses or housings, etc.).
