64 Dart Trunnion Boot

I have not tried yet, but I did bookmark a couple of "how to" sources on just replacing the boot that should be helpful:
Ball and Trunion Refresh...A Tutorial

How to Rebuild a Ball and Trunnion Drive Shaft | CCRC
I like the one from the B Bodies site. That's a goodun. I don't know. I may press the pin back out. It's not like it's difficult and I do have a press. I won't know what I'll do till I get there. LOL
