With postage, those buttons (which are in US$) come to about AUD$56 - so not too bad.
I'm not sure if the stalks will be a problem, mine don't seem to be angled the same way, or is that the angle of my photo? Using the pull-toward-driver functions does bring them much closer though:
It may be a problem for the windscreen washer. I don't normally flash my lights, so I can live without that. I'll find out, I suppose, when the buttons arrive and I can see how thick (or rather, hopefully thin) they are.
Now to play the waiting game.
