A third BT24 chassis had been built at the end of 1967 but was only used in three races by the Brabham team, twice for Rindt and once for a one-off appearance by Dan Gurney. Kurt Ahrens, Jr. hired the car from Brabham and entered the 1968 German Grand Prix, before it was acquired by Frank Williams and modified to take BT26-style wings and a 2.5 litre Cosworth DVW V8 for the 1969 Tasman Series. Piers Courage drove in all seven races, winning at Teretonga Park in New Zealand and finishing second, third and fourth with three retirements in the other races to finish third in the final points standings.
