Good to know. Will save me having to ask in future when the back disc needs changing.

 

The 98-06 disc arrived a few days ago. It was about $33 from a Chinese supplier on ebay. It fits my 2009 perfectly. Thanks for all the info. It really helped me out as I couldn't find a supplier able to deliver an 09 disc to my location and wasn't certain which years and models would be suitable alternatives.

As the 98-06 wasn't advertised as compatible I initially thought it wouldn't fit an 09 but it seems the only differences are it's floating rather than solid and is 0.5mm thinner, which I can live with.
