Also, it seems like some on eBay have the hook that lets the derailleur hang on the axle, but some don't. Can I use the one that is on the Allvit?
Only if you replace it with another vintage Huret. Huret had a stop point on the hanger at four o'clock and all the other manufacturers use a mounting plate with a stop at the seven o'clock position. Another case of where Huret and others do not mix.
