what is the condition of the ball joints and the arm bushings?

you dont always need the spreader bar for alignment. it basically mimicks road load and spreads the wheels apart from the front. It was useful on old optical machines or hanging alignment. The new hunter machines are great and if the operator is sharp they can do it quite easily without the bar.
