After the immediate success of the GT 1300 Junior, Alfa Romeo decided to use the same recipe also with the spider range: at the same time as the 1750 Spider Veloce, the Spider 1300 Junior, equipped with the 1290cc 4-cylinder engine, which delivered 89 horsepower, also made its debut. . The 1300 was a simplified version in many respects and was consistently less successful than the 1750. In 1969, like the 1750, the 1300 Junior was also modified with a short tail body.
