Shoot me straight on center links?

Have a 67 with a slant K. Have Schumacher mounts to put in a 340. I’m converting from manual to power steering. Found a power column same year, and now my local U pull it has a 73 valiant With power steering and drum brakes. If I use the box from the 73, what hurdles will I have to jump? I read my 67 k has a 1 year only pitman, but I also read I’ll need a large sector pitman and matching idler arm from a 73 up. Do I need to get the center link also if I take the ps box, and will a 73-76 idler/pitman fit my 67 k if I do go that way. If anyone can square me up on this I’d appreciate it. Btw I’m not using headers, I have a set of hp manifolds if it’s relative. Thanks guys...
