On your old setup the thicker spacer was to make up the difference between a Shimano cassette and a MAVIC cassette, the thinner spacer was for the difference between a Shimano 10-speed cassette and a Shimano 8 or 9-speed cassette, the 10-speed cassette is narrower. Not sure what you need to mate up a Campy cassette with a MAVIC Campy compatible freehub. My guess is no spacer, I don't think MAVIC cassettes were built with the Campy spline pattern.
