I don't believe Yakima has released a fixpoint system for the 4G yet. I too, am anxiously waiting for these - I spoke to my local dealer (Rack Attack) and they were saying it'll probably be a few months at a minimum before Yakima releases something for our trucks that mounts to the pre-drilled holes.
In the meantime, I'm exploring the option of just making a custom mount for a 6063 1.5"x3" extrusion. I've got a trip planned for next month and really just need a set of bars to transport our kayak.... but really don't want to get a full roof rack to do so.
