1. With the convertible top in the up position;

- Release the rear bow latch,

- Release the rear stowage lid and raise to full up position,

- Prop rear bow of convertible top in up position.

2. Locate and remove the original bumper from the flange on the hinge box and discard (see illustration Views A and B).

3. Obtain new bumper P/N 15679393 and, using a hacksaw, cut a slot 7 mm (9/32") deep and 1.5 mm (1/16") wide in the bumper as shown in the illustration.

8. Install the hose on the hinge arm as shown in the illustration so that it will make contact with the bumper when the stowage lid is open. The open side of the hose should face inboard. NOTE: View 'C'.

9. Repeat steps 2 through 8 for the remaining side of the lid.

10. Close the stowage lid for 20 minutes, allowing the adhesive to cure.
