Arturo Merzario
The entry of 28 cars had to be trimmed to 22 before the race, and those who failed to qualify were, unusually, from six different teams. They were Clay Regazzoni of Shadow, Beppe Gabbiani of Surtees, Arturo Merzario in the car bearing his name, Héctor Rebaque in a privately run Lotus, Rolf Stommelen of Arrows and Michael Bleekemolen of ATS.
