The steering shaft connection is accomplished using the included universal joint. The joint is installed onto the steering box so that the set screw is directly over the groove in the input shaft. This end was temporarily secured using the supplied set screws. On the steering column end of the U-joint, insert the steering shaft all the way through the joint collar, but no farther than about 1/8-inch past. If the shaft extends too far into the U-joint it will cause binding. Mark the position of the U-joint through the set screw holes with a marking pen, as shown.
