I think the OP wanted to go with '73 and up stuff, for the bit more clearance it offers at the headers and oil pan; so the later centerlink and manual pitman arm will get him there.
Having seen the clearance with both styles of center link it's really 6 of one and a half dozen of another. There are clearance issues with the 73+ stuff too, just in different spots. Biggest issue it looks like the OP has is the center link being flipped.
It would probably be easier to keep everything 73+ just since that's what the car is, but the center links aren't reproduced so you'd have to source a used one. And the pitman will have to be for a 73+ manual box if a '73+ center link is used.
The pitman and idler are readily available, so, that might be a quicker solution even if it meant keeping the '67-72 center link. Just throwing out options. All you have to do is make sure you match the pitman and idler to the year of the center link.
