No, not according to what he posted. The pieces that must go together (except a 67 only K member) are the center link, idler and pitman arm, and the steering box. The studs on the idler and pitman arm point upwards vs downwards in the 72/ earlier vs 73/ later, and of course the splines on the steering box must fit the pitman arm.
Key words here is "center link." If you can not change that, then the box/ idler/ pitman must fit the center link
