Subject: PROCEDURE FOR REPLACEMENT OF D-81 "AERO-WING" SPOILER

Models

Affected: 1987 - 1989 FIREBIRD
This bulletin supersedes bulletin 89-10-10 dated 2/89 which had a wrong part number on it. Please discard bulletin 89-10-10.

Primed spoilers, P/N 20681851 and 12397143 may be received with no obvious mounting provisions for the CHMSL (Center High Mounted Stop Light).

Examination of the mounting area will reveal two small raised bumps. With a small sharp blade (x-acto knife or equivalent) carefully trim away surface skin to reveal the molded-in threaded inserts.

Do not attempt to drill new holes, install inserts or use sheet metal screws; material displaced by such modification will usually result in distortion of the top surface.
