There was a total of 718 in 1988. They have the same engine options available as the GTA (350 TPI with Auto, 305 TPI with Auto or 5-speed manual). The Notchback was simply an appearance package that was only available on the GTA, so besides the fiberglass decklid and the special rear seat tops (which also was later used on the 1989 Turbo Trans Am), the Notchback is a GTA elsewhere and shares the same features of a GTA. http://www.gtanotchback.com
