That depends on which autodrive plate we're talking about. If its pre-drilled, you'll need the pivot/axial. If its the red, silver, and blue aluminum one from a few years ago, you can put any binding on it.
I'm assuming that by "pivot" you mean P14/Axial140, not P18.
I don't know if I'd dump a pair of FKS bindings, which are great bindings which will soon be in high demand (due to their discontinuation), just because they don't fit on a pair lackluster Skicross 9s. If you're looking for an allmountain ski and you've already got the bindings, maybe you should consider looking at allmountain twins like the Public Enemy or Dynastar Troublemaker, both of which can be found on ebay for reasonable prices.
