The leading Edge Mean Aerodynamic cord (LEMAC) is 1143 inches aft of the datum. The lateral balance is measured in inches and is referred to as buttline. There is a right buttline and a left buttline. Note that the landing gear is some 432 inches from center to center. The wingtips are 1864 inches from tip to tip.
