A4.2.2 BODY ALIGNMENT
The illustrations on pages 11 - Body Dimensions PLAN, and 13 -Body Dimensions SIDE VIEW, provide specifications
for damage assessment and location of replacement parts.
These dimensions must be strictly applied whether they are used for damage assessment, component location or post
repair verification.
The plan view MASTER datums are nominated on the right
-hand side of the body with the left-hand datums dimen- sioned from them. Therefore, the right-hand datums must be known to be correct before any other cross-ar dimen- sions are checked.
W: The right-hand side is always looking towards the front, from the rear of the vehicle.
All dimensions are derived from a single
(ZERO) datum point for all three axes; X for length, Z for height and V cross- car.
