I am guessing your tracker has the 16V engine, right? If so, you will need the PS setup off of a 16V engine, so the belts will line up. You need the pump along with the engine bracket, the steering shaft between the firewall and steering box, the steering box with pitman arm, the crank pulley (if yours doesn't have the dual crank pulley), the lines and the reservoir. And you will need to get a new belt. Then it is just a matter of bolting it all on and bleeding the air out.
