ORDERING LABELS THROUGH WDDGM

Beginning November 1, 1932, for cautionary and informational labels which were previously ordered through Helm, Inc., became available as regular parts and accessories through the WDDGM systems. Refer to GM Parts Bulletin 82-144 for further information regarding ordering labels.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
