The worst part is that the parts are now made by Ford.They were originally sourced from another supplier but they stopped manufacturing them(approx $80),now Ford manufacture them and they've more than doubled in price.
Thanks to all who posted, did try ford spare parts who told me it only came as both sections - cruise control + audio and quoted $208. Wreckers/junk yard would be an option, but where I live there is a very limited selection, did think of ringing around the Melbourne wreckers. In the end I did a repair job with the super-glue (not shure how permenent this will be, but almost 1 week now and still o.k.) it was a very delicate operation (should have been a brain surgeon!!!) thanks russelw for the part number and price, if the repair doesn't last I will now be armed with the right info.
