dont forget the harrier engine for the back
i have the Star Wars Chronicles book
the base of the tracks are flat but theres some detail on the top, they kitbashed alot of things to make the films, like theres some panther cupolas on the Seeker (the thing Luke trains with, with his lightsaber)
and the B29 fusalage on the Rebel mecical frigate
just look at anything that looks close for the tracks like they did in the film
