steering box

68/ later, you can put any year box on the K frame, and include 67 with "some work"

What changes is the later boxes are larger spline, so you MUST have the larger pitman to match. Since this is the later one, you then need the later center link and pitman to match.

The early setup has the pitman/ idler attaching nuts on the top of the center link. Later is pointing down.

You can use the same tire rod ends and sleeves.

On a 67 K, if you need the later "stuff" you'll have to fabricate the idler bracket, as it's "one year only," and the later stuff won't fit.

Example, for the present, I'm using a 73/4 K under my 67 to get the later idler mount and spool engine mounts, but I"m using the earlier center link/ small spline box.
