1969 Alfa Romeo T33/2 Spyder
In 1969, Autodelta converted a number of 1968 cars to spyder configuration for continued use. The resultant design was very similar to the T33/2 Daytone minus all the bodywork above the windscreen base. This configuration was chosen for the 1969 Targa Florio which sometimes these cars are named after.
The new body was fitted to a chassis very similar to the 1967 car with its large-diameter H-frame chassis that also carried the fuel. The 270 bhp, 2-liter, aluminum V8 was retained to avoid a costly engine development program.
