General findings: -Nearly all center of coach measurements exhibit more curve than the two end measurements. - The above is true generally for both sides (driver & passenger). - Early coaches (1973 and to a slightly lesser extent 1974) coaches exhibit the greatest amount of body curve (some to an extreme). - Coaches were measured with roof pods and without roof pods. No significant differences found. - Measured low mileage and high mileage coaches. No significant differences found. - Late coaches (1978) seemed to conform closest to the design dimensions.
