Slip yoke question

Leak at rear of c4 in my 65 with 302.
Replaced the seal, but not the bushing around the slip yoke. Still leaking. Before I tore it apart ran it but local transmission shop, does a lot of classics.

He questioned the orginality of the slip yoke. Also said its very worn. Noticeable grooves in the yoke.

Going to order a new yoke but wanted to make sure I got the correct one. I assume a 28 spline for 65 C4 289 will work? Only question is some listing state specific u-joints which makes me wonder why the variation.

Just like to order everything once and be done.
Last Pic the diameter of the current u-joint which may be irrelevant if It's wrong slip yoke.

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.

awesome thank you. I looked online and having a hard time finding inside snap ring.. called dallas mustang, they're nearby. nothing there either. they said not in production anymore because they were "unsafe" but try a transmission shop they may be able to help.. will keep looking

I do plan on replacing the bushing as well. I also noticed one other leak at the shift lever right by the NSS. Going to fix it too even though it's really small.

I'm not finding a source for the internal clip yoke anywhere. so I can across something else.
would this work?
combination u-joint

If i'm seeing this correctly. it would allow a internal clip on the drive shaft but outer clip on new yoke, which is much easier to find.
