!!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."
