I'm with Os. Slide the sleeve off the stem, cut it into about 1/3, 2/3 pieces. Slide both pieces on your mainline, put the 1/3 chunk on the top, and the 2/3 chunk on the bottom of the float. Seems to fix it pretty well onto the mainline, although it will slide when you make a hookset, so you'll have to readjust.
