Power Steering Box and Pump $75 obo SoCal

Best way to tell is it a early p/s box or later model p/s box... Measure threaded shaft diameter or what size socket fits the nut under pitman arm. If your 1&1/8 socket fits it, it is a early type box with 3/4 ( .750 ) NF threads there.
If you need a 1&5/16 socket for that nut, its the later model box with 7/8 ( .875 ) NF threads there.
