Some front end questions
Only thing I know to do is point you back to your original thread:

Here's the general idea
You can use ANY 67 and later K member in ANY A body 67 and later, except that the 67 has a one year only inferior mounting for the idler. You can fabricate that so it takes a 68 / later idler
So far as 68 / later with the later K frame bracket, you must have THREE items "matched." That is the center link, the idler, and the pitman. Look at the diagrams in my post
What dictates which pitman you use is by whatever you have for a steering box, IE large or small spline shaft
The rest of the parts "could be mixed." That is, if someone has converted an otherwise "early" (67-72) setup to the late 73/ 74 disk brakes, you will find you have 73/ later upper / lower ball joints, late upper A arms and of course spindles and bearings, calipers and rotors, etc
You REALLY just have to check this stuff out. If there is any question, get it apart and measure it (such as bolt hole spacing on the lower ball joint) and post it here
Tie rod ends and sleeves don't matter "all that much." They pretty much all fit as long as you have a "pair" of inner and outer and the matching sleeve.
My car is a good example. As a 67 it went from there to "only" a 73 K member for the better mounts (a long story.)
When I got time I converted it to disk brakes, so the upper arms, ball joints, etc got changed, and a sway bar was added.
Now that it's torn down for paint it's going to go "back" to a late model power box. This has a large spline so NOW it will get a 73/ later center link and idler along with the box and pitman.
