Exactly! They were leading the 1.5L class, had an off during lap 254 and were assisted back on track by spectators.
The sister car (#42) led the class until it crashed on lap 243 and retired.
They would have been classified as 10th & 11th overall as well as 1 & 2 in class.
The retirement(s) allowed the #47 Porsche 550 Spyder (Zora Akus-Duntov was one of the drivers) to win the class, placing 12th overall and completing only 216 laps.
As the French would say:
c'est dommage.
