The next thing to do is to complete the sides. To do this, you'll have to cut the sides from the sprue, then clean them of the flash and knobs on the backs of them, then remove the steps and other bits as shown in the photo. The top side is completed in this regard, whereas the bottom one is freshly cut from the sprue. The arrows show what has to be removed from the sides. You'll have to file wherever you've cut things down too, as when the paint is applied, any rough patches will show up like a flare.
