Tom Belsø replaced Galli in Sweden but he only took part in practice (and was slowest) as it appeared no funding was available from his sponsors for the race. Ganley crashed in the warm-up and finished eleventh in the car Belsø had used. The car had received a new cooling system before this race. Henri Pescarolo returned to replace Belsø for the French Grand Prix, but retired with overheating problems while Ganley finished 14th. Graham McRae replaced Pescarolo for the British Grand Prix, qualifying on the back row, but he retired with a throttle problem on the first lap, while Ganley started 18th and finished ninth.
