Some women think jewels are beautiful-guys like us admire truck parts in much the same way. The drop pitman arm we had previously used didn't fit on the new box so we had to search another one down. A week later, we had four different pitman arms-none of which fit our steering box. Finally, both Revtek Suspension and Icon Vehicle Dynamics came up with the solution at the same time, both providing us with the correct one. The arm turned out to be a unit designed to fit Super Duty model years 2000-2004.
