Just to be clear. The pitman is connected to the main steering shaft of the steering box. The idler arm is like a winge on the opposite place of the steering box.
You can buy a brand new steering box at astronomical prices in Manila or you can buy a good surplus from the U.S at much less cost. Garyq and I have the same opinion. I dont want to spend more than i should on a steering box that is suppose to last as long as the engine and its drivetrain.
