just whatever you do, do not allow the bracket nuts to break loose and then you have a big problem. I did the install this weekend and the nut came loose from the bracket so in turn it was just spinning as I spinned the Bolt. I had to open up the sight hole slightly so i could get a vicegrip in to hold it while I turned the bolt. This is NOT a fun job if this happens!
