Gear box and prop
Front diff, drive shafts, hubs, and sump.
Clutch cable different aswell i think.
I know you can use to 2wd rear diff but not sure if the ratios are the same so probably easier to go for a 4x4 one instead.
And keep it off the grass
Coverted mine from 2WD to 4x4 and although its slower in a straight line and not as much fun its not outweighed by the ability to go out in the rain without fear of death
