so i finally installed these; i've had em kicking around for a while now.
ordered em up from quadratece. they were like 50$ after shipping or something. they are aluminum. painted them. pain almost matches the jeep; but i dont' care lol.
step one: measure where you want to put louvers.
step two (optional): have a few beers and try to measure where you are about to cut your perfectly good hood up.
cut your hood up. just don't cut to much, that way you can really butcher the cutting job (like i did) and nobody will really know.
step four: attach louvers. i used rivets becuase they work well and i'm lazy.
