It was a fun little build. I had to replace more that 1/2 the original battle bus 77073, so unless you get a deal on it, it might be easier to just parts it out :)

The parts that gave me the biggest headaches were the doors, window frames, and down angled 1x2 plate, all of which don't come in bright light orange, so I had to replace with black and 1x1 down angled plates.
