This is a good shot that illustrates how we tied the center of the rear bulkhead to the footboxes. The weakest point in the chassis is right under the doors (because there is no roof there). We had to make the cockpit area as stiff as possible to make up for it. We did that by tying the sides of the rear bulkhead to the front of the footboxes and the center of the rear bulkhead to rear of the footboxes. We couldn't tie the center of the rear bulkhead to the front of the footboxes because they changed angle at that point to spread out around the engine.
