Why not just buy a new bracket from: http://www.styleandperformance.it/
It's about 120 Euros + postage. You can even specify what colour you'd like (Such as Silver if you have a Silver swing arm ), then buy a Brembo caliper of your choice. The cheapest are roughly $150 and widely available (Even used).
The fulfilment of orders with S&P can take a while, but that's just Italian mentality, I guess.
Then again, it'll take longer and probably cost a more to get any alternative bracket elsewhere, so...
