Some 962s were even more extensively modified, with several open-cockpit versions being developed in the mid-1990s to run under new sportscar regulations. Kevin Jeanette built the Gunnar 966, mimicking elements from the 917/30 Can-Am cars. Kremer Racing would once again develop their own chassis, with the open-cockpit CK7 running in Interserie and K8 running at most international sportscar races, including Le Mans and Daytona. These cars shared little with the original 962s, using custom bodywork and chassis designs, yet retaining the engine and some suspension elements. Heinz-Jörgen Dahmen converted his 962 (chassis 011) to an open-top version that he raced in the Interserie in 1995 and 1996. The car had previously been campaigned by him in the Interserie since 1990.
