Corporate Bulletin No.: 031067


Subject: INFORMATION ON T-TOP WEATHERSTRIPS AND ATTACHMENTS


Model and Year: 1982-91 CAMARO


TO: ALL CHEVROLET DEALERS


The following information in this bulletin will clarify the correct parts usages for T-tops weatherstrips, retainers and butt joint attachments on 1982 through 1991 "F" style vehicles.


The information will identify the differences between:


^ 1988 1st and 2nd design weatherstrip and retainer attachments

^ 1982 through 1987 and 1989 through 1991 usages

^ recent panel weatherstrip changes and usages


NOTICE: The parts for 1st and 2nd design MUST NOT BE INTERMIXED. The weatherstrips and retainers are specific to each system and if mixed, will not provide correct butt joint attachment support.

Figure 1:

1. The 1988 1st design weatherstrips and retainers have interlocking slider brackets (see Figure 1). This design was used on approximately 1,000 vehicles in the 1988 model year. However, due to potential confusion in recent years, some service repairs may have been made by intermixing these parts with 2nd design parts.

Figure 2:

2. The 1988 2nd design weatherstrips and retainers DO NOT HAVE INTERLOCKING SLIDER BRACKETS. The butt joints attach to support mounting plates on the body (see Figure 2). The 1988 2nd design parts are the same applications for the 1982 through 1987 and 1989 through 1991.

3. Recent changes to the weatherstrip on the removable roof panel removed the locating tabs and revised the molded ends. The part number was changed from 20680014 to 10165420. This component is used with either 1st or 2nd design systems.


IMPORTANT: THE ILLUSTRATIONS CONTAINED IN THE BODY PORTION OF THE 1989 THROUGH 1991 SERVICE MANUALS DEPICT INCORRECT WEATHERSTRIP RETAINERS FOR THE MODELS CONCERNED (SECTION 10-8 ROOFS).

Please update your Service Manuals accordingly.
