Correct center-link for 74 duster 360

Is center-link, pitman and idler arm different for drum vs disk brake?

Is center-link, pitman and idler arm different for manual vs power steering?

In my case here, can I just replace the driver side pitman arm to 67-72 and it will be good to go?

Many thanks
I found out the center links are different the holes are also have to point one way or the other they are both tapered but face either up or down .. so screwed up..:violent1:
