Not so sure if they're available for the 04-06 because there's so much fairing. There was a set on my RR4 when I bought it, BUT they go through the fairing into the engine mount. I've taken them off. Quite prepared to let you have them for postage only, which could be about 6 quid because it includes the longer bolts. (That will mean you have to drill you fairing which I sense you might not want to do)
