It's not 6 vs 8, it's 73/ earlier vs 73/ later
OK you already know the 72K uses the old style "pillow" engine mounts. Also, if you have or want to use an anti roll bar, the 72 K must use the "underneath" type bar, and the connection tabs for that on the LCAs are different than 73 / later K
Everything else will bolt up, UCA LCA, etc etc
Now on the steering. You MUST have a pitman that matches the splines on whatever box you are using. The 73/ later pitman must use a 73/ later idler and center link. Has nothing to do with 6 or V8 except I think B/RB maybe.
The tie rod ends will interchange either early or late, so you must match the box, pitman, idler, and center link. On the center link, the tapers on the tie rod ends point the opposite way between the 73/ earlier center link and the 73/ later center link

does or have any one swapped the complete steering from a 70 duster to a 73 if so are there any issues being the two center links are different
