Long story hashed to death here - but there is a Yakima set of risers that will work with this rack to mount one of their units. Just out in the last year or so.
Or, they are limited to what Subie will sell them for their proprietary rack.
By the way, I don't suppose anyone knows why the photo I just caught on top of the Yakima site pictures white water kayaks in a desert...
