I did hood louvers/vents on a previous 4wd once. Never again. When ever I'd drive through a big puddle or bog hole, steam would come gushing through the vents and onto the windscreen and sometimes reduce visibility to zero.

HOT DAMN. THAT THING IS TOUGH! Do you have a Build Thread? cause your TR4 is badassss

I think it looks pretty cool, especially since they are homemade. If I were to do them, I would probably have them punched on a louver press though to avoid the sharp points, and add structural integrity, but the ones you did definitely add to look of your truck.
Here are the louvers I had punched in stainless for my ‘65 Cobra replica.

Looks good. I wasn't sure how the riveted look would work, but it fits in well with the style of your truck.
These are the vents I used years ago. They were fiberglass and came from a Ford Cosworth. I glued them on.![]()

i think i saw this posted in the facebook 4runner group.
What CSX# is your Cobra? Running a 302 or 429? Helped a friend in CA restore his original back in the day for his collection. I'd sell my organs to buy his.
