I have about 6 different types of tail wheel assemblys on different planes so if you look around you will find A lot of choices. What I showed you was just something that may have come in A kit at one time and I just addapted it to the plane. Most my tail gear uses springs attached to the pull/pull system for turning. If you are landing correctly you won't have any problems with it the way you have it but in time the hole in the rudder gets loose. You can install A piece of brass tube in the rudder next time to keep that from happening. See, just so many ways to do something.
