spindle question

Just so I am following correctly,did you obtain the 10" spindle along
with the lower ball joint/steering arm? IIRC the lower ball joint changed as well as the
bolt hole orientation between those years,or maybe between 9" vs 10" ? I don't have
any 10" drum knuckles here to eyeball,just early and late 9" and the '73&up disc,......
