Art, I bolt them to the factory hole in the frame. The hole is forward of the big suspension adjusting nut and it is in the corner of the package tray. If you use that hole the harness will be at a slight angle to the seat so one side of the harness will need to be longer. Either type will work but the Y type is easier. The other way to attach them is to weld a 3" angle iron between the frame rails about 5" behind the 4x4 upper frame member (under the package tray). This allows the harness to go straight back at the proper angle. All new frames have this piece welded in.
