2005-2013 Corvette Convertible Header Trim: Latch, Fitment, and Interior Color Guide

Symptoms of a Failing Header Trim Panel

While this panel is generally durable, it can fail over time due to sun exposure, stress from the latch mechanism, or accidental damage. Signs of a problem are typically cosmetic but can affect the top's operation.

• Visible Cracks: Hairline cracks or larger fractures may appear, especially around the high-stress area of the central latch handle opening. These are often caused by repeated use and heat cycles from sun exposure.
• Rattling or Squeaking Noises: If mounting tabs on the back of the panel break, the panel can become loose. This will cause rattling or squeaking noises from the windshield header area, particularly when driving over bumps.
• Cosmetic Damage: Scratches, scuffs, and discoloration from UV exposure are common. This can detract from the interior's appearance.
• Poor Latch Operation: While usually a problem with the latch itself, a severely broken trim panel could potentially interfere with the smooth operation of the latch handle.

Is It Your Trim Panel or Another Top Issue?

Many C6 convertible top problems are often misdiagnosed. Before replacing your header trim panel, be aware of these common related issues that are NOT caused by the trim panel itself:

• Tonneau Cover Hits Rear Window: A common issue where the folding hard tonneau cover makes a 'clunk' sound by hitting the glass rear window is caused by stretched elastic tension straps inside the top assembly, not the header panel. A TSB was issued for this, and the fix involves modifying or replacing these straps.

• Headliner Tearing: The fabric headliner can get caught in the top's frame and tear, particularly at the corners. This is a design flaw with the top mechanism and requires headliner repair or replacement.
• Top Fabric Separation (2008-2009 models): GM issued Technical Service Bulletin (TSB) 08312A for 2008-2009 convertibles where the top fabric could separate from the front retainer bracket at speeds over 100 mph. This requires a specific reinforcement repair and is not a fault of the interior trim panel.
• "Flying Roof" Recall (Coupe Models): A widely known recall (GM #09230) was for 2005-2007 coupe models where the adhesive on the removable roof panel could fail, causing it to detach from the vehicle. This does not apply to convertibles.

Buying a Used Convertible Top Header Trim Panel

A used OEM panel is often the best choice, as it guarantees a perfect fit and color match that aftermarket parts may lack. Pay close attention to these details when buying used.

1. How to Verify Your Interior Color

Matching the interior color is critical. Corvette C6 interiors came in several colors like Ebony (black), Cashmere (tan), and Titanium (gray). You must verify your car's specific color code before buying a used panel.

1. Open the glove box in your Corvette.
2. Look for the Service Parts Identification (SPID) sticker. It is a white or silver label, usually located on the inside of the glove box door itself.
3. On the sticker, look for a list of three-character Regular Production Option (RPO) codes. Near the bottom of this list, you will find a code that ends in the letter 'I' for Interior, or you can find the trim code listed separately. For example, common codes are 193 (Ebony), 313 (Cashmere), or 843 (Titanium Gray).
4. Match this code to the code provided by the seller of the used part to ensure a perfect match.

2. Physical Inspection Checklist

• Check for Cracks: Carefully inspect the entire panel, paying extra attention to the area around the center latch opening. Flex the panel slightly to reveal any hidden hairline cracks.
• Inspect Mounting Tabs: Flip the panel over and check that all plastic mounting tabs and clips are present and intact. Broken tabs are a major red flag, as the panel will not sit securely and will rattle.
• Look for Sun Fading: Compare the color across the entire surface. Uneven fading or discoloration indicates heavy sun exposure and may not match your existing interior trim.
• Examine the Latch Opening: Ensure the cutout for the latch handle is not broken, chipped, or excessively worn.

Cost of Replacement

Replacing the header trim panel is a manageable project, but costs can vary. Here is an estimated breakdown:

Replacement Overview

Replacing the panel is a feasible DIY project for those comfortable working with interior trim. The general steps are as follows:

1. Disconnect the Battery: This is a precaution to prevent any electrical issues, especially if your car has an auto-dimming mirror or lighted visors.
2. Remove Sun Visors: Unscrew the mounting points for both the driver and passenger sun visors.
3. Remove A-Pillar Trim: The plastic trim panels on either side of the windshield (A-pillars) typically need to be gently pried off or loosened to allow the header trim to be removed.
4. Remove Latch Handle: The center convertible top latch handle must be removed. This is usually held on by a few screws.
5. Unfasten and Remove Panel: The header trim panel is held in by a combination of clips and possibly a few screws. Carefully pry it away from the windshield frame, starting from one end and working your way across.
6. Installation: Installation is the reverse of removal. Be sure to align all clips before snapping the new panel into place.
