Three-Dimensional Measurements

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

Three-dimensional measurements are provided in the absences of dimension information from your equipment supplier. Universal 3-dimensional measuring equipment is required to use these numbers. You may need to adjust the height dimensions to match the datum height of your equipment. Only the width dimensions can be used to measure point-to-point. All holes, slots and fasteners are measured from the center.
