• New optional on the GTA was a new "notchback" hatch: rather than the large, glass hatchback that had been common to the Third Generation Firebird, the optional notchback consisted of a fiberglass trunk lid with a small, flat, vertical glass window. The notchback also incorporated redesigned rear seatbacks with integral headrests. 


  • A total of 718 of these Notchbacks were built in 1988. Produced by Auto-Fab of Auburn Hills, Michigan.
  • The notchback was canceled for the 1989 model year.
  • production records in 1989 indicate that a few were produced.
