I am not sure what the issue is but it seems to be fairly arbitrary and random based on the threads I have read. One threaded nearly the entire way by hand, the other went one turn. If I had to guess, both are probably machined to pretty close tolerances with a plus or minus. If you end up with a male and female pair erring on the opposite ends of the ranges they won't go together. I had to walk away yesterday before I launched one over the fence but I am going to try swapping and see if I can split the difference.

Unfortunately, no machine shop close by. I will probably purchase Moog replacements for $40 if I can't get them to go today.
