A thought. Many, older, steering box sector shafts are obsolete and extinct. As are the thrust bearings. I've rebuilt a few, early Bronco, PS boxes. Core condition varies widely. Finding "usable" sector shafts and spools is increasingly difficult. Also, the recirculating balls are selective in .0002 increments. I'm not aware of anyone having these made, or an OEM source. I was forced to modify INA iglide polymer thrust washers to replace bearings. There is a difference between reassembled and remanufactured.
