Hi KWC,

Than sounds like a piece that you'll only get with the kit,doubt that you'll be able to get a new spare part for that alone.Maybe ask around at your club if anyone knows a fellow member there or elsewhere whether they have the same plane or similar that's been crashed(usually the tail survuives) and you could most probably re-use that piese or else not,you might have to remake the whole thing the old way it was always done in the built up kits.
If you need any further assistance,let me know.

Good luck
