Montlhéry 1981 historic cars event (ASAVE). Looking for programme with list of cars and participants

Hello everyone. I have a set of interesting photographs from a historic automobile event held at the Montlhéry circuit in France in 1981. Some of the cars can be identified, but many vehicles are difficult or impossible to identify from photographs alone due to similar bodywork, rebuilds, or replicas. I have also seen video footage of this event on YouTube. I would like to ask if anyone has any information or sources where it is possible to find a list of participating cars (makes and models) and, if available, participants. This could be an official programme, entry list, archive, document, book, or magazine. Any information or references would be greatly appreciated. Thank you in advance.
