The anti-lacerative windshield which was previously used on all 1986-87 Rivieras has been eliminated for this carline, effective with the start of the 1988 model production. The anti-lacerative windshield was removed to improve customer satisfaction related to damage resistance, cleanability, and decal removal.
The non anti-lacerative windshield, Part Number 20685206, should be used to service all 1986-88 Riviera models.
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.
