what parts do you need pretty much the only thing that's changed is the gears in the transmission
and the carriers /steering knuckles and axles
I just updated a 1994 rustler to run the new hex wheels other than that its perfect the way it was
if you plan on running brushless you may want to buy a new style trans with the metal gears
they are cheap
