If you can find one you'd be better off putting an X caliper in there as the design is much better - just make sure you get all the spacers as well because they are different.
x caliper is the same on the re from 05 or 06 onwards. mine is of an 07. and they are much better designed. I think it was to stop pistons seizing and wrecking seals..
only need the one spacer, the one that fits against the caliper mount. be warned these are £15 each. I had to have mine shipped over from yam in japan!
