French Touring Car Championship

I wonder if anyone knows of a website that contains details of races held in the Championnat de France de Voitures Production, the French Touring Car Championship, for Group 1 style cars. I am particularly interested in races between mid 70's and early 80's.

touringcarracing.net does have some information but in certain years just quotes race winners. If anyone knows of a site, even if its in French, I would be grateful.
