Upper ball joints

OK, look, the center link / pitman / idler and steering box must all "match." These parts have NOTHING to do with any of the rest of the front end, except 67 which is a one year only idler arm

In other words you could have ANY year K member, (except maybe 67) you could have drum or disc brakes, spool or biscuit mounts, does not matter.

That is, you cannot put the later center link "matching group" on a 67 unless you mod the idler bracket on the K member to take a later idler arm.

The above mentioned parts must all go together, and are determined primarily by the steering box BEING USED that is to say, large or small spline pitman shaft.

The LCAs so far as I know only matter based on "if" they have and what type of tabs for the sway, that is the early sway bar goes under the K, and the later one goes THROUGH the K member. The tabs on the LCAs for the early K are on on the high edge of the LCA, the tabs for the later bar are on the lower edge of the K

My own car is a good example of mix/ match..........

67 Dart

73/4 K member, late sway, late LCAs

but earlier small pitman shaft box, and 68 style idler, pitman, and center link.

Search around, "Oldmanmopar" posted some excellent photos of K members and other suspension pieces some time ago
