oldvolvosrule helped me out for the rest of this season, but if anyone would like to trade, the step-in kit is still available (I don't care too much for it, I'm find with the standard).
I have a complete step-in systems for Catek OS1/OS2: it includes the heel receiver, the toe bail. I would trade it for a standard heel bail, heel block and toe bail/lever (the toe blocks are the same).
