id say mine has about 4 or so positions of open. back goes to about a 3-4" opening. and i can pop the glass out all together and stuff it between the shotgun seat and the cab wall. its nice to do at a redlight. people have mixed reactions to seeing that. anyways, i spent about an hour making sure it was going to be centered, square and even all around. then i eyeballed it for preferance. also made sure it wasnt going to have the visors over the opening when they're up. i chose to remove my headliner to check for any cross braces. there arent any there. just a perimeter brace around the roof edge. center is open. i sorta trashed the headliner taking it out. ill try and get it back in after i modify it to work in there. that wont be too hard i dont think. probably just notch the bars to go into the inner sunroof ring/clamp.
also, for the pop up style, for some extra money, i know they make a style that pops up in the back, then slides back on a track above the roof. so its sorta like a big spoiler. but i like the pop out myself. little bigger would have been nice.
mine is about 16x32" at the edge of the frame outside.
