Due to a running change, there are two possible types of headliner and lace systems for the 1991 Pontiac Grand Prix. Installation of the old style lace (9.5 mm wide) is illustrated in Figure 1. Installation of the new style lace (17 mm wide) is illustrated in Figure 2. Please note this information in the appropriate Service Manuals.
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.
