68 kframe vs. 73 & up

Pitman arms and idler arms are a booger to keep sorted. The 67 idler arm is what it is, different from all others. 68 to 72 are the same in how the mount to the K and to the drag link . 73 to 76 pitman and idler still the same at the K but different in how they attach to the center link. So yeah the center link changed in 73 up. Having fun yet ? If you stick with manual steering you'll probably get it together but, if you get the later K with a power steering gear on it you may find yourself searching for a pitman arm that was never made. You wouldn't be the first. Hope this helps. Good luck
