Good thought process John. If it does touch, you may need to recheck to be sure your steering gear box was correctly centered before attaching the arm to the shaft. Should have the same number of wheel turns left and right from center. I seem to recall that the gear box arm isn't straight up and down on the shaft, but angles slightly to the rear when wheels are straight forward. That placement may be why your arm contacts the brake line hose in the full turn position. Possibly a question that may need more discussion in the Driveline forum.
