Yup! They're so rare they are worth their weight in gold! New or used! Actually it's the 4 towers and the 2 cross members and the various hardware to bolt them on that make up the OEM roof rack. I got mine from a forum member parting out a wrecked VX.
I think the other things you were talking about are the Yakima Mighty Mounts. They're the oval shaped things that fit on the cross members that attach other accessories like a bike or ski rack. They did NOT come with the OEM rack and they're not available now, so, again, there's a pretty good demand for those when they come up on ebay or here.
