Instead of a using a custom sleeve, here is a thread from a member who found a way to do it with a replacement tie rod end you can get at a normal parts store.

Now now this guy was putting a 71-72 brake setup on a 69, so I did a little reasearch before posting something I might regret later. The 67-70 tie rod ends are the same as 65 and the 71-72 tie rod ends are the same as 73-up.
