the 2009 had 34t pulleys and 20t centre so the belts were (507 and 183)different to the 2008 (38t pulleys and 16t centre) and T3 (38t pulleys and 20t centre), there was a conversion to 38t pulleys which would give the standard belt sizes used today (513 and 189)

you may struggle to get the top deck pieces now but you can fit a T3 12 top deck with a little filing and drilling of 2 holes as I did to mine to give more flex.
