I traded my 63 cm Motobecane Grand Jubile frame, with Suntour VX dropouts, for a slightly smaller Jeunet frame with relatively plain dropouts (thanks, Justin!). The Jeunet dropouts do not have a derailleur hanger.
I would like to use all the Campy NR gear I have kicking around, including a derailleur that I took off the Motobecane.
So my question is, what kind of derailleur claw do I want? Can I use one off a cheap Suntour derailleur, for example? If so, are there any particular tricks I need to know about?
