Idler arm confusion

!!NO!! It is not the K. Here is the deal:

confused, steering gear compatibility

67 K is one year only and has a special idler arm
68--72 K uses pillow engine mounts
73/ later K uses spool engine mounts

Between 68--72 THE STEERING LINKAGE can be swapped IF you keep the idler, the pitman arm, the center link, and the pitman arm spline to fit the steering box "all together"

In other words you can swap those parts "together" all the way from 68--76

But they must be kept "together."

Yea I found the k is a pillow mount 68-72 but the linkage is different. Is a manual pitman arm spline the same as between the years? I have a line on a correct 68 center link and picked up an idler arm. Do the tie rods intermix between the years?
