перенести меню в шапке с права на лево

добрый день!
сайт http://design-vsego.dp.ua

не могу пенести меню в шапке в правый угол – так как тема свестрана не совсем мне понятно!
используются z-index и я пока в этом ничего не понимаю.

куча текста – и что здесь отвечает за положение менюшки – не могу понять!

помогите пожалуйста!
