You will need a '68-'86 C series or a '87-'91 R series steering box and pitman arm. As for the pump, that will depend on what water pump your engine has. Keep in mind that the fitting style changed in about 1980 from SAE to Metric with an O-ring. It is easier to plumb if both the steering box and pump have the same style of fitting. You will also need the mounting brackets for the pump as well as the pulleys to drive it, belt and hoses. connecting this all to yout draglink will depend on whether you still have the original or have upgraded to disc brakes. And of course you will need an adapter plate to mount the steering box to your frame.
