hey guys, i need some help! i just recieved my westin nerf bars for my 2004 150 supercab xlt, but the instructions seem to boggle me! my frame beam underneath looks nothing like the frame beam on the instruction manual from westin. their's show that their beam has some sort of ledge where the brackets sit on and screw in, but my beam has no such ledge, it's totally square (or rectangle), with no place to set the brackets. there are holes though for the screws. please help.

 

The brackets don't bolt to the frame. They bolt up under the rocker panels in existing holes that are covered with rubber plugs and black tape.

 

you are absolutely right, thanks man, i'm a bone head!! or just too excited! later!
