I have a 2004 ram 1500 quad cab hemi 5.7 4x4
the truck did not come with nerf bars on it. if I buy a set will I have to have brackets welded on? or drill holes in the frame?
My aftermarket nerf bars came with everything I needed, No welding or drilling holes. I don't quite know about older trucks. You could always try and get the instruction manuals from the brand you are thinking of to see how they are installed.
