 Note on the chassis number 
 Team Tyrrell had three cars (701/2, 701/4, 701/7), and in most of races all three were tried during practice. 
 From the Spanish GP on, March had 701/6 as the team spare. 
 March’s own chassis records disagree with contemporary race reports and there is disagreement, too, among contemporary race reports as to the occasion on which Stewart used 701/5 and 701/4. In fact, 701/4 was never raced in its original spec, although it appeared in practice, but its racing history was undertaken with a 20 swg monocoque, thus the choice to give it the designation 701/4-2. 
 After Siffert crashed in the French GP, 701/5 was given a new monocoque, but this was the tub which had been originally fitted to 701/1, which had been repaired after Amon had damaged it in practice for Monaco. 701/1 received a new monocoque for the Belgian GP and this has been designated 701/1-2 (for Amon). Siffert’s car with the tube from 701/1 has been given the designation 701/5-2, but it could be argued that 701/5 disappeared and the car which Jo Siffert drove after the French GP was actually 701/1 and 701/1-2 was a new car. 
 701/11 built up from spares and bits and pieces from Peterson’s car (701/8) for Mordaunt Clark Racing with Alistair Guthrie who entered Mike Beuttler in F1. Before the end of the season 701/11 was converted by the works to F5000 spec. 
 Frank Williams’s 701/6 received new tub (Tyrrell spare) after Oulton Park crash.  | ||
