Rear deck lid luggage carrier rail nuts may pull out of the deck lid at the rear, outer locations on 1983 and 1984 6000's and 2000 Sunbirds (see illustration). 1983 vehicles used a 5mm screw/nut and 1984 vehicles used a 6mm screw/nut at this location.
To repair this condition, replace the nuts with the new luggage carrier jack nuts, Part Number 14007940, for the 6mm screws and Part Number 1623436 for the 5mm screws.
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.
