Airborne,
I believe the tiller extension mounts are available from Layline or APS. I got mine from RWO, can't get anything from them now. If you search under my username you can find some more close up photos of the self tacker and bow foil. The Tacker came from a Tiger, and the foil I built. I sail single handed and the self-tacker works great for that. Spinnaker is in the process, building molds for the spin hoop now ( half is done) carbon pole is done. All standing and running rigging has been upgraded to new and sometimes old but good ideas. The standing rigging I did myself (it had to be custom). But you can buy OEM standing rigging from Layline or Murrays. The 5.2 is a great old boat (IMHO). Have fun with it.
