i got my trunk cage but didn't get any instructions with it. a little confused about the mounting points on either side of the stock subwoofer. does anyone have pictures of their set up and where specifically these two bars mount. also didn't get any mounting hardware for the main trunk bar at the very back.....anyone know what size bolts to use when mounting bar to body or are they existing factory bolts there.......again just got the bars and haven't taken anything apart for a good look. pics on the web on various distributor sites aren't all that helpful......thanks in advance.
