a place called stockers in san diego has them in stock....
100 bills though... he seems to be well aware these crack all the time and there is no aftermarket solution.
Once I get my hands on one, there WILL be an aftermarket solution... 
Do you need one at all for modeling or do you need an uncracked one?
ill mail you my cracked 350 top if you are planning creating a solution for us!
I'll take you up on that offer: I have a friend with a CNC who would like to get into making billet parts for bikes. There are billet top trees for many of the big sportbikes, selling for $80-$500, depending on fancy. I wish to make one billet top tree with 2 alternate mount holes so it can fit both the 400F and 350F, so it has a shot at the market. It needs to sell about 4 per year to make it, so the costs can be recovered in a reasonable time. After typically 10 units, the costs are covered and the money man is paid back: after that it's a viable 'product'. It went like that with several other products I've developed with other folks, some motorcycle, some not. This one might take a little longer, as there is no "market" to sell into, it just has to spread around by the need. But, there are not a lot of these tree tops around, and they break for lack of proper tightening, so that gives an opening for a superior, wrench-proof version to appear.
