I'm pretty sure you can find an America owner to trade the parts with. The wheels, fork leg, caliper, master cylinder (though some say this isn't necessary) and all the little bits. When I found my TBS wheel I traded everything but the wheels with a Speedmaster owner who already had spoked wheels.
Also, if you're worried about stopping ability go with a floating rotor and an aftermarket 4pot caliper (Beringer?).
