I found an over the counter solution. Here is my tie rod after the 2.5" arm stretch.
You can see how little thread engagement there is.
This is the ES440S sleeve compared to the stock ES2004S. The ES440S is an old Chrysler part 74'-82' New Yorker part.
With the ES440S there is plenty of thread engagement. I would say it could handle a 2"-3" arm stretch.
And there she is installed.
