Got it, metric seatpost bolt and Suzue hubs. Sorry if I caused confusion.
Not sure which Campy derailleurs you have but most older Campy rears will not take up a lot of chain slack. I have an old Campy on one of my bikes and I have to run a very small freewheel because I put a triple on that bike. A larger freewheel with a triple will not work with the small cage derailleur I am using. The Campy front that I am using works with the triple, but it was designed for a double and I am near the limit of the range for what it will take. Thus, you might be best off using the Huret parts that you have. If you have problems with that rear Huret, older Suntours are around on the used market and would work well in the back.
