3 Racing Sakura D3 CS Drift

Hi all,

I just scored a D3 but i'm in need of some parts. Does anyone know what size belt runs off the front diff pulley?

I was stalking rcmart but they have two front belts listed for the D3, #sak D-114 (138t) and #sakD-115 (183t)

Also can you confirm if it is a 38t pulley on the front diff?

I'm still waiting for the chassis to arrive and i haven't found a manual for the D3 yet..

Thanks
