I just put one on my wj and I had to drill one side of the clamp that is on the tierod
to take the new pin or you could turn down the shoulder of the new pin but i don't have a lathe at home and couldn't be bothered taking it to work I was also told that you need to add aspacer but I couldn't see where or why mine clears from lock to lock and dosen't seem like it will hit when flexed hope this helps
maybe bill would have more info
