Install a Sullivan Tailwheel. I mounts on the bottom of the fuselage and has a spring that extends out to the rudder and inserts into the wood on the bottom of the rudder. This will give you a steering tailwheel.
These are the tailwheels that I prefer because the spring isolates the rudder from the tailwheel in case the wheel is jammed or jerked to the sides. It prevents damage to the rudder.

Ditto! I personally dont like the tailwheels which glue into the rudder. Feel as if its something you'll have to fix later!
