One of the real wrenches (instead of a mere former owner of French bikes) will know more about this, but I went through a Peugeot/Motobecane stage a few years ago and my experience was that nothing I ever wanted to use fit anything. The stem on French bikes was 22.0mm, instead of the then-universal "1 inch" (which was actually 22.2mm; go figure). That's not much (I even filed down a steel mountain bike stem to fit when I converted a Motobecane to a town bike), but it screwed up just about everything I tried to do.
Tks, I agree :( their velo-decline is justice. nmsprockets2

If you go threaded you may still be able to get a HS from Campy that will fit. If you go threadless you'rem ost likely SOL unless you bore out the threads on a lathe. Not a hard thing to do really. You can do it if you really want. King may make one custom for you.

Seems to me there are two possible solutions.
1. Get a carbon fork that is threaded to match the French-thread headset you have. Look is French made, but I don't know if they made a fork with French threads. If they do, it will be a special order. This solution seems unlikely to pan out.
2. Get a carbon fork and a new headset. The compatibility issue will be if the inside diameter of the headtube shell on your bike matches the current standard. LBS should be able to measure the inside diameter of your headtube and any 1" headset to see if it will work.

By the way,
I needed a new headset for my '79 Peugeot project bike and was able to order one from Stronglight. Threads matched perfectly.
Also, Phil Wood makes French thread cups for their excellent bottom bracket. These guys really helped me out with my project bike. Great product, great customer service.
