1989 - 1990 Corvette: Service Bulletin: Convertible Stowage Lid Not Flush With Rear Deck

Source: Chevrolet Dealer Service Bulletin
Number: 90-183-10 - (02/20/1990)
Subject: STOWAGE LID NOT FLUSH W/REAR DECK-PROCEDURE & STEEL RIVETS
Model Year: 1989-90 Y Car Convertible

Some 1989 and early 1990 Chevrolet Corvette Convertibles may exhibit a height difference between the stowage compartment lid and the rear deck. This condition may be caused by a lack of adhesive between the steel inner reinforcement and the stowage compartment lid inner panel.

CORRECTION:

Remove the stowage lid as outlined in the Service Manual.
Drill 8 (eight) equally spaced 1/8 inch holes through the vertical surface (See Figure 1) of the stowage lid inner panel and the reinforcement.

IMPORTANT: Use a Drill Stop Set at a Depth of 1 inch when drilling these holes in order to prevent damage to the compartment lid.
Install 1/8 inch diameter X 1/4 inch long STEEL rivets in the holes.

IMPORTANT: Do not use aluminum rivets as they will not provide the strength necessary to keep the lid from bowing.
Coat the rivet heads with touch-up paint to prevent rust.
Replace stowage lid as outlined in the Service Manual.

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.
