74 to 67 disc brake swap

Hello,
just trying to get some more info on what i will need to complete brake swap from a 74 dart to a 67 dart. I have a donor 74 v8 dart that i pulled the front brake rotors, upper & lower arms, spindles, prop valve, master cylinder and lines.

From what i've read some say that what i have so far is all i need. I've also read that i may need to get the steering box, pitman arm, idler arm and center link so everything lines up. I've also read that the later model steering linkage and p/s gear box wont fit the earlier cars. Hoping to get some clarification on this matter before i don't have access to the donor car anymore. Thanks for your help a body fans
