I replaced the TTB on my 86 F-250 with a dana 60. It was a good fit, but required at least 3" of lift to clear the engine cross member.
I am not sure if the drag link from the D60 will connect directly to your steering box. I did high steer on mine.
Another item to note is that there was no need for a panhard on the TTB setup, so you will need to find a way to get one installed to prevent bump-steer.
TLDR: It looks easy on the surface, but doing it correctly and safely takes a bit more work.
