Abstract: A center upper frame node connector, which can be a casting, can comprise: a forward horizontal upper frame node oriented in a first forward direction; a rearward horizontal upper frame node oriented in a first rearward direction opposite the first forward direction; a rearward angular upper frame node oriented in a second rearward direction and a first downward direction; a vertical upper frame node oriented in a second downward direction; and a first connection pad on a first side of the upper frame node casting and a second connection pad on a second side on upper frame node connector opposite the first side. The center upper frame node connector can be coreless, that is, without any hollow portions at any of the frame nodes and either of the first and second connection pads.
