I know it's not a Firebird, but my '66 Le Mans has a factory blue interior. Dash, dashpad, door tops, pillar trims, sunvisors, headliner, console base, grab bar, seats, seat backs, steering column, steering wheel center cap, carpet, kick panels, package shelf...EVERYTHING is blue except the instrument cluster bezel and console top.
