Just checked the XRay parts lists for T3 2010, 2011, and 2012. The part numbers listed above are standard for all T3's.
Having just removed my 'Forward Motor Position' conversion from my '009 (I use it as my wet car. The joys of racing in the UK
), which i had to fit at the time to use the 38t geardiff I had.
I wanted to keep the 38t pulleys etc. as it means I can use the Spec-R geardiff I had going spare.
So if you are going to use 38t pulleys with 20t layshaft pulley;
The belts you need are the standard items from the T3 series.
Front 305432 - 513mm
Rear 305446 - 189mm
They're the ones right up to the current T3'12
