CANSPO will continue to carry replacement glass panels, as well as replacements for the new acrylic tops. The new acrylic T-Top panel part numbers are as follows:

Right Side: 12505684 Left Side: 12505685

Some 1989 models were built with acrylic tops and some were built with glass tops. All of the 1990 models were built with glass tops. If replacement of a 1989, 1990 or 1991 model T-Top panel is necessary, replace it with the same "type" of panel as there are slight appearance differences between the glass and acrylic panels.

IMPORTANT: THE NEW ACRYLIC TOPS SHOULD BE USED TO REPLACE ACRYLIC TOPS ON PREVIOUS MODEL YEAR F-CARS WHEN NECESSARY.

While the new acrylic panels have a special hard coating to resist scratching, they still require special care when removed for stowage or cleaning.

- Flush off dust and dirt with water and then dry.

- Clean panel with GM #1050427 or equivalent. Allow cleaner to remain on panel for about one minute, then wipe dry with a soft lint-free cloth.

- DO NOT USE ABRASIVE CLEANERS.

Use applicable Labour Operations and Times from the Canadian Labour Time Guide.

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.
