Initially for 1987, only 5.0L U.S.-bound GTAs could have T-tops installed; they were not, according to the order sheets, available in any Firebird model with a 5.7L engine. Again, this was a weight issue dealing with the CAFE ratings. GTAs destined for Canadian delivery in 1987 were not bound by the same requirements, and were available with the 5.7L engine and T-tops.

According to Pontiac order sheets and production records, the only GTAs subsequently available with both the 350 TPI engine and the T-top option were the 1989 model cars; the GTA that year enjoyed a large build number with both options. Starting in 1990, all 350 TPI GTAs were available as hardtops only.
