That kit from EBay doesn't come with the lower aluminum chassis plate or the steering bellcranks by the looks of it. Besides screws, basically you need the upper and lower chassis, all steering components, fuel tank support/structure, and a few more odd parts. I'll try to pull up the exploded view and highlight the parts you need. The suspension, shock towers, transmission, engine mount, battery box all transfer from the sport to the rustler. The chassis and steering are the only real differences I believe. I will double check for you though.
