From memory, you would need:
Side & Rear belts
Centre & Rear Lower Transmission housings
Chassis, lipo cradle, battery posts, straps & top decks
Centre Layshafts, slipper plates and misc. bearings
Motor mount & side gears
Side belt tensioner
Bodyshell & under tray
And a few parts I've probably missed
So there is quite a bit that is different, and there mainly the expensive alloy/carbon parts
