You might try talking with a small Ag Leader dealer, who might separate a SteadySteer kit, and remove the "hard parts" , because he might know that he can sell the cables separately, to a farmer, who only wants cables for a 2nd tractor.

A dealer did it for me, when I wanted more parts, for 2 complete SteadySteer systems, verses moving SCM, steering wheel motor, and GPS7500 globe/reciever, back and forth between a JD8410 and JD4440 tractors.
