Don't see a current mention in http://www.bipac.net/page.asp?content=tag_title_toolbox&g=SEMAGA It is 7" in PA
NY has an "obstruction of vision" law that a cop can give you shit for blowers, injector stacks, hood scoops, etc., even those fuzzy dice hanging from your mirror if he/she wanted to be a prick. As far as windshield height???? I wouldn't push it in NY, they're broke and look for anything they can make a buck on.
