### Inner Rear Wheelhouse

The Camaro/Firebird convertible inner rear wheelhouse assembly is replaced at the factory seams.

### Outer Rear Wheelhouse

The Camaro/Firebird convertible outer rear wheelhouse assembly is a 1-piece assembly consisting of the wheelhouse with a forward that attaches to the door opening frame and inner rocker reinforcement.

To simplify service when the vehicle is only damaged in the rear portion of the wheelhouse assembly, sectioning can be used to install the service part. The procedure requires removing the forward flange from the new assembly so it can be installed onto the still-attached flange of the original part.

### Removal Procedure

1. Remove all related panels and components including the quarter panel.
2. Visually inspect the damaged area.
3. Restore as much of the damage as possible to factory specifications.
4. Remove the sealers, the sound deadeners and the corrosions materials as necessary.

Important: Note the number of welds for installation of the new assembly.

5. Locate, mark and drill out factory welds as necessary.
6. Apply a strip of 25 mm (1 in) wide masking tape along the inner surface of front wheelhouse, approximately 380 mm (15 in) up from the base of the wheelhouse.
7. Cut the wheelhouse alone the outer edge of the tape.
8. Remove the damaged section of the wheelhouse, leaving the forward flange.

### Installation Procedure

1. Prepare the new rear wheelhouse assembly by removing the forward flange. Leave approximately 7 mm (1/4 in) on the lip running along the outer surface of the wheelhouse.
2. Prepare the mating surfaces of the new assembly.
3. Check for proper fit.
4. Cut the new wheelhouse along the corner of the bend.
5. Remove the unused section of the wheelhouse.
6. Drill approximately ten 8 mm (5/16 in) holes for plug welding every 40 mm (1.5 in) along the cut edge on the new wheelhouse.

Important: If the original component is damaged beyond recognition, and the location for replacement welds is unknown, locate the weld holes 35 mm (1 1/2 in) apart.

7. Drill holes in the remaining locations as noted from the original wheelhouse panel assembly.
8. Position the new assembly.
9. Check for proper fit.
10. Plug the weld wheelhouse.
11. Clean and prepare welded surfaces.
12. Apply the sealers and the anti-corrosion materials as necessary.

Important: Do not combine paint systems. Refer to the manufacturer's recommendations.

13. Prime with 2-part catalyzed primer.
14. Install all related panels and components.
