the extra bolt hole in the pump is normal. if it is a p/s box, it will be more difficult to steer without assist than a manual box. if it has no hose looped, or plugs, it has been run dry, which is bad. if it has not been run dry, all you need is a pump, a bracket for it, a way to drive the pump (correct pulleys and belt) and a pressure and return hose....and some fluid. it's not difficult. even if you have to replace the box it's not that hard, just costs more. or you could put a manual box on it, which would necessitate a different pitman arm and ragjoint at least.
