Most Huret RD's were intended to be mounted with a nut behind the DO even on threaded DO's like Huret and Campy. The extra threads are for the nut. The proper way is to tighten the nut on the inside, while leaving some clearance ouside the DO for the RD body to rotate. Lots of times, especially on used bikes, the RD gets mounted without the nut, preventing the body from rotating. The RD still shifts, but you can't rotate it out of the way to change the wheel.

I have a Huret Jubilee rear derailleur with what appears to be the original hanger bolt for a Campagnolo drop-out hanger. I also have the special purpose-made "claw"--the stop that fits over the bolt, with adjusting screw, to position the derailleur properly.
The problem is, the hanger bolt appears to have too many threads on it. When I tighten down on the thing it tightens all the way down, rendering the derailleur body immobile. I know this is not how it's supposed to work...it's supposed to work like a Campagnolo or Suntour..the derailleur is supposed to rotate around the bolt, because the threads end and the bolt stops just short of the derailleur body, leaving a bit of room for the derailleur to move.
Any solutions, anyone? Like, a bolt that will actually work right in this configuration?
I'd really like to use this derailleur.
France is a lovely place, but I really hate the french for their insistence on making their stuff *different* from everything else. Different threads. Different steerer-tube sizes. Different SEAT tube sizes. Different seatposts. Different drop-out hangers and derailleur mounting methods. It's just perverse, imho.
