Have you not read the Mopar Suspension book? It's all in there. Pitman arm angle is fully adjustable by utilizing front end shims between the box and K frame. Likewise, the idler arm is adjusted by filing the holes in the K frame to reposition the idler arm. There are specific measurements from the floor to the idler arm and pitman arm. These measurements must be the same on each side. Also, there are specific measurements from where the outer rods attach to the floor. It's all in the suspension book. Been in there 40 plus years.
