In retrospect, of course that's true. I need to recheck that. The best solution is find a press long enough to deal with longer head tubes or, on my cheap Amazon Porsche, find a replacement threaded rod to extend it (I suspect difficult).

In my experience, Suntour sprockets (as well as most other freewheel brands) wear first on the spoke side. This is basically impossible to detect except on the largest sprocket, unless you remove them from the body for cleaning. When you see wear on the outside, usually there is significant wear on the spoke side. The first two sprockets on ProCompe and Perfect bodies are threaded and are completely interchangeable. The threading and diameter are identical to threaded sprockets used with New Winner, Winner Pro, and Winner bodies in the second threaded position. These are interchangeable as well. Only the 13T and smaller threaded sprockets on NW, W-P, and W will not fit on ProCompe and Perfect bodies. I should have a decent 17T in my spares and will check later this morning and post a picture. It might not be a match in color, but it will certainly get the job done and should solve the issue. While I'm hunting, I'll see if I can find and post pictures which show the wear difference between the spoke-side and the outside of the sprockets.
Thanks for all that detail, and the PM. While getting a 17T and a chain whip would be the affordable solution (I am in about $200 in on each of the project bikes and am still hoping to present them to the owners for $0), I am reading carefully the "wear on three sprockets". While I do not expect the Gitane to get heavy use, if it really needs 3 sprockets changed, is replacement of the entire FW smarter?
