Here's a 1991 Pontiac Firebird Trans Am convertible in Bright White.
1991 and 1992 were the last years for the Third Generation F-bodies. The Fourth Gen cars were already in development and, although they were derived from the Third Gen cars (in much the same way as the SN95 Mustang platform was a heavily-revised Fox), they featured significant improvements.
One problem the 3rd Gen F-bodies had is that there wasn't room for a 5-speed manual gearbox that could handle the torque of the 5.7L TPI motors, and so '91-'92 were the last years for the LB9 Tuned-Port Injection 5.0L.
Rated at 205 SAE net horsepower, this fuelie 305 was the only motor available in the Trans Am convertible. Presumably this is because the convertibles were actually converted from coupes with a roofectomy performed by American Sunroof Corporation in Michigan and the torque from the 245hp L98 350 would have twisted the frame like a pretzel without the stiffening provided by the roof structure.
