I have a NOS pair of Simplex Prestige SLJ 5500 front and rear drailleurs. T he rear doesn't fit the tab on my bike's braze on. I would like to trade th em for a pair of Huret Jubilee derailleurs in excellent or NOS condition. I need the rear derailleur bolt to be the kind that threads into the frame, not the kind that slips through and fastens down using a shallow nut on the other side.
Hope this interests someone. I'm dying to get this bike on the road.
