67' to 73'+ Disc Swap Question

So I may not have been clear, I'm looking to keep the steering stuff I have for right now if possible, car only has 18k miles, but kinda doing a proactive "while I'm in there refresh". Would love to do the entire steering too but I'm a broke college kid so that'll have to wait until I graduate.

Just trying to confirm that a 73+ lower control arm fits a 67 valiant since I know 67 used a bunch of random 1yr only parts.
