NEW T-TOP WEATHERSTRIPS WITH DRAIN PROVISIONS AT BUTT JOINT

Subject: NEW T-TOP WEATHERSTRIPS WITH DRAIN PROVISIONS AT BUTT JOINTS

Model and Year: 1982-91 CAMARO WITH CC1 OPTION

1991 "F" style vehicles built after the following VIN breakpoints will use new T-Top roof opening and panel weatherstrips.

ML186669

These new weatherstrips have a drain system added to the butt joint contact areas on the opening portion of the weatherstrip, and use a new butt joint angle at the contact areas, see Figure 1.

The new panel weatherstrip also mounts in a new retainer. The new retainer is slightly longer than previous styles and has slots in the outboard surfaces to better retain the tabs on the outer ends of the weatherstrip.

Due to the change in butt joint angles, these new components MUST NOT BE INTERMIXED WITH PREVIOUS MODEL MATERIALS:

OPENINGWEATHERSTRIPS - 10165494-5(RIGHTANDLEFT) PANEL WEATHERSTRIPS - 10165496 (COMMON TO RIGHT OR LEFT) WEATHERSTRIP RETAINERS - 10198230-1 (RIGHTANDLEFT)

This new weatherstrip is retained to the roof with new type locating brackets at the butt joints on the roof opening. Figure 2 will provide some basic dimensions for bracket location.

Parts are expected to be available on September 2, 1991. Until then normal part orders will not be accepted by GMSPO. Only verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be cancelled as incorrectly ordered while the 400 control is in place.

While it is possible to use the new weatherstrips and retainers to replace past model materials, it is NOT necessary to use the latest mounting brackets if repairing earlier models with this latest material.

1. Keep in mind that the opening and panel weatherstrips must be used AS A SET due to changes in butt joint angles.

2. The upper ends of the garnish moldings will need some material removed to clear the new butt joint shapes.

In addition to the above information, a new service kit is available from GMSPO, P/N 10164133 and contains the following:

Right and left roof opening weatherstrips Right and left panel weatherstrips Right and left panel weatherstrip retainers Right and left sealing strips (awnings) Instruction sheets

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.
