### Removal Procedure

Riviera's unique quarter panel styling requires a special sectioning procedure that improves serviceability.

1. Remove all related components, including the quarter glass.
2. Cut a 700 mm (28 in) long tab in the quarter panel beneath the roof panel following the upper character line of the quarter panel (1).
3. Note the location and number of all factory welds except those along the 700 mm tab.

Drill out factory the welds and remove the damaged quarter panel.

### Installation Procedure

1. Bend the 700 mm (27 5/8 in) tab down slightly (1).

The new quarter panel will be welded to this flange (2).

2. Trim the upper mounting flange on the new panel so that it can fit properly over the 700 mm (27 5/8 in) tab from the original part.
3. Position the new panel and check the fit.
4. Plug weld accordingly.
5. Weld the new quarter panel to the 700 mm (27 5/8 in) tab.
6. Clean and prepare welded surfaces.
7. Apply sealers and anti-corrosion materials as necessary.
8. Seal the joint between the roof panel and the quarter panel with an appropriate material.

Important: Prior to refinishing, refer to GM 4901MD-99 Refinish Manual for recommended products. Do not combine paint systems. Refer to paint manufacturer's recommendations. For further information or to order Manual, call 1-800-269-5100.
