You need the 65-66 internal clip style, which had smaller bearing caps than the 67-73 external clip style. And yes, your slip yoke is trashed, although I've seen worse. Replace the bushing while you're at it. With the correct tools, replacing the bushing only adds about half an hour to the job.
Amateur restorer. Well, sometimes I have been paid for it. But not right now.
