Since you have already attached the bracket... there's only a few options.

The above wheel collar method needs a bit more explaining... to connect the steering to the rudder, replace the set screw with a 1 inch or longer machine screw. Bend a wire "yoke" to cradel the screw and link to the rudder for steering. A bit of fuel tube on the screw acts as a slight shock damper. (more of a "feels good" than actually does any good...)

If the rudder isn't on the plane yet, you can extend the tailwheel wire up appx 2 inches above the bracket, make a 90 deg bend close to the bracket, and another 90 appx 1/2 inch from the end of the wire. This last bit gets imbedded in the rudder using epoxy, then a strip of light fiberglass or medium silk over the wire and bottom of the rudder will lock it all together.

There's also a way to drill a second set screw hole in the wheel collar and affix it using two 1 inch screws, then springs from pens for a fully shock isolated steering link on the tailwheel. (look at some of the fancier tailwheel brackets... same idea, just inexpensive..)
