Barney,
Those C&A mini skis really improve the handling, along with carrying the front end better when the snow gets deeper. I got some aluminum mounts for the skis from Tony at his now defunct Bullheadmoto shop. You should be able to make them fit by using some other C&A mounting kits, but you'll probably have to end up removing the metal stopper that's welded on the bottom of the a-arm so that the C&A ski will fit. With his aluminum mounts it moved the ski down so that clearing that plate wasn't an issue.
If you do pick up some C&A skis, do not use any of their carbides with the SnoScoot. They are way to aggressive, and really make it hard to turn. Contact Bruce at CB Performance. He made me some really nice steel wear rods for these skis that work great.
