Here are a few pics of mine. I looked for a long time and never really found one perfect. I finally bought the rugged ridge light bar that swivles so you can move the bar up and down. When I first put it on, it sat way too high, and way too far out from the windshield. I ended up hacking it up and cutting off some tube to shorten it, and remounted the brackets so that it tucked in closer to the windshield. I'm super happy with the way it turned out. I especially love the fold down feature just because it alloys me to pull in the garage.
Personally, looking through that quick thread, I hate ever single light bar in there! If you notice, every single one is way higher than the roof line, and sticks out way in front of the windshield. I don't think its a matter of stock or modified, just make it look clean. It needs to look like it belongs on the Jeep, not like it was just slapped on there. I first had the normal white hella 500s up top, but they stuck out like a sore thumb. Everything on my jeep is dark if you notice, so I forked out the money and bought the black magic 500s. They look way better up there.
You would have to drill a hole in the windshield frame. And fish it through that way. Just use a rubber grommet to fill the hole and keep water out. I think that will look really good. I've seen that bar before and imo it looks good. Nice and low, nice and tight.
