I found a dealer with one 0size and a number of 3 size bolt heads. He wants $AU25 each for them. He had about 10 or so.
I don't want to get a group buy going on this as there isn't a lot available. The size 3s are normally very expensive (and scarce).

PS I forgot to mention, I am going away for a few days, I don't know if I'll be able to get on the net.
