It started life as a Chevron B36. It then got modified and turned into the mess pictured to comply as a C2 class car for 1987.
It was entered as a Chevron B36 #TJ01 ROC by Thibault and driven by José Thibault and André Heinrich and lasted 18 laps before crashing.
Not sure what engine it ran,Talbot Tagora is part of the entry name, but suspect is was a cossie or a BMW.
