I need a CZ GP rear brake relocator set for my SP2... bracket, Brembo caliper w/ pads.

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. :D

Then again, it'll take longer and probably cost a more to get any alternative bracket elsewhere, so...
