At the 1970 Monaco Grand Prix, in May, the works and Tyrrell cars were joined by a new yellow and maroon March 701, chassis 701/8, that March had sold to Colin Crabbe's Antique Automobiles privateer team, on condition that Crabbe ran Swede Ronnie Peterson in the car. Stewart qualified 701/2 in first place and Amon chassis 701/1 in second, with Siffert and Peterson 11th and 12th, respectively. Servoz-Gavin failed to qualify for the 16 car race and, fearing that his eyesight was failing, he retired from Formula One. In the race Amon held on to his position until his rear suspension failed on lap 60 of 80, while Stewart had retired three laps earlier than Amon with a broken engine. Both Peterson and Siffert were classified at the race conclusion, although they only took the final two positions in seventh and eighth, and Siffert had already ground to a halt having run out of fuel on lap 76.
