Corvair Fitch Sprint
John Fitch was given the opportunity to test several models of the brand new Corvair during the fall of 1959. He had the cars for two weeks and tested them at the Lime Rock track in Connecticut. During this prepublic tryout, John left enthused with the Corvairs potential as a Grand touring machine with a European flavor. He then set out to develop various engine, chassis and body modifications. John decided to market these modifications and the Fitch Sprint was born. John’s first Corvair was a 1961 Monza coupe. John used this car as the basis to build the first prototype Sprint. Fitch Sprints were available in three different flavors. A customer could have his new Corvair drop shipped to Fitch’s Falls Village shop and have Fitch’s mechanics install the Sprint kit options desired. Or, the Sprint kit could be installed by a local Chevrolet dealer who is authorized by Fitch to install the Sprint kit. Fitch recalls that more cars were converted at dealerships than at his shop. And lastly and most popular, you could mail-order the kit and options you desire and install the Sprint kit yourself. Fitch continued producing Sprints until GM pulled the plug and later sold all inventory and tooling for the Sprint to Art Hershberger of Solar Automotive in November 1971.
Fitch Sprint Options
Options are broken down approximately by year introduced, but be aware that there is some overlap across years. Fitch produced these parts over approximately a 10-year period from 1961 to 1971 until he sold all rights, parts and toolings to Art Hershberger of Solar Automotive. So any year Corvair could have any of the following options that were not early or late model specific.
