1. A method of manufacturing a load structure, the method comprising:
forming a panel having a first side and a second side;
clearing a fill passage through the panel, the fill passage extending from the first side to the second side, and the fill passage is defined by an interior wall of the panel;
providing a tool having a first tool portion, a second tool portion, and a cavity disposed between the first tool portion and the second tool portion;
connecting a fill bushing to the first tool portion or the second tool portion of the tool, the fill bushing includes a flange;
disposing the panel within the cavity of the tool;
disposing the fill bushing within the fill passage of the panel such that the flange of the fill bushing engages a portion of the interior wall;
connecting an injection gun to the fill bushing; and
injecting a material, via the injection gun, through the fill bushing and the fill passage such that one of the first side or the second side of the panel is at least partially covered with the material, the fill bushing is arranged within the fill passage to block the material from contacting the other one of the first side or the second side.
