Sheldon Brown has a good article on French Bikes pointing out few obsolete threads and diameters: if it is an early 80s road bike, chances are that the BB will be English threaded, but the stem diameter and seat post diameter (narrow 25 mm) will most probably be narrower than standard ones. Nothing that cannot be sorted out with some patience and a sand paper.
