with 3 little hex screws on each corner. you can easily take them off to clean behind them. i never looked on my Roush, (didnt have it long enough to need to clean behind them) but from outside appearance im guessing that there is some sort of a bracket that mounts onto the window glass that the screws go into, b/c if not, where the are located would make them go into the glass! so there must be a bracket you stick on the window with 3M tape or something, and then screw the louvers to that. im going with the roush louvers on my 06 when i get it. liked them the best from the ones i saw.new stang owner said:How do the Roush's attach. THey seem bigger than the window.
I've got the Generation II Louvers. Depending on what you get, you may or may not be able to see out of them. The Generation I & II's have slits cut out so you can actually see in and out, making visiblity ok. Other brands have fake slits, no seeing out or in...not good. Mine attach via 3M auto tape, good stuff, covers just the glass part of the quarter window, no attaching to the car body at all. Sending site link, scroll down a ways to find the Generation Louvers.scoutbb said:Do these louvers obstruct view or can you see through the blades? if it obstucts your view, backing out of a parking space will be a little difficult. I plan on getting a '05 GT and curious on which ones to get.
