The easiest would be to use 63-70 conversion spindles and use your 1965 centerlink and tie rods.
71-72 or 73-87 is going to require the same year ball joints and tie rods to be swapped.
You would also need a used 71-72 or 73-87 centerlink. These aren’t sold new.
Then you’ll need to swap pitman arm and idler arm.
It’s a domino affect.
The 67-70, 71-72, and 73-87 idler arm mounts differently on the frame. You’ll have to locate it a drill new holes.
Do you currently have some of these parts?
