I am looking at outting 4" lift springs front and rear on my 70. Will I need a 4" drop pitman arm? This rig is manual steer, BTW, so I foresee problems finding an arm for it. Also, what will a 2" body lift do to my clutch linkage and column shifter???? Thanks for any help, I'm getting tired of my "burro" getting sand kicked in its face.
