In 1983, several changes took place with the design of the Mustang In 1983, the alternate option to a T-top was the flip open roof. These were the only options to a plain roof, unless you wanted a convertible.
The first Mustang convertible in 10 years was produced this year. It came with a power top and a glass rear window. This car was outsourced by Ford to Cars & Concepts. The basic convertible was the GLX with a 3.8L V6 engine, however, you could also get a GT convertible.
As long as we are on the engines, the default engine was the 4 cylinder 2.3 L. A new V6 3.8L engine was optional, as was the 5.0L engines. There was a 2.3L Turbo engine as well, but you could only get this engine in a 3 door Turbo GT.
