A laser beam plane generator is provided and supported from a datum line vehicle body reference point measuring jig for generating either a vertical longitudinal laser beam plane parallel to the vertical centerline plane of the vehicle body, a vertical transverse laser beam plane normal to the datum line, or a horizontal laser beam plane. A hand-held wand type probe is used in conjunction with either of these laser beam planes to check and/or verify the spacing of specific vehicle reference points relative to a selected laser beam plane.
