A French bike of that era will have metric pedal threads - 14mm x 1.25mm.
That's close, but not close enough, to the modern 9/16" x 20tpi standard,
as you found out.
Your best bet is probably to replace the left crank with a non-French one.
Alternatively, you might be able to have the crank rethreaded.
Sheldon Brown has a useful page on older French bicycles that lists some of
the other incompatibilities you might encounter:
