What you must do. The tie rod ends point the opposite direction between 73/ later and 72/ earlier. There are 4 items that must be compatible to use the linkage
Steering linkage can be 68--76 but you must split it as so:
Determine what pitman it takes to fit your steering box, large or small spline. Whatever pitman you have access to, 72/ earlier, or 73/ later, use that center link and idler arm. In other words those 4 pieces must match, box, pitman, idler, and center link. You can use any year the tie rod assemblies, and you can not use a 67 idler which is by itself because of the K member mount.
