Thanks for the info, I think it's just a matter of getting the right clips. I'll take any Yakima rack that has Q-towers.
I purchased the one with the round cross pcs. Go with scare tubes if you have a choice. My kayak sport racks turn on the round tubes.I put a small dent in my roof! Hal
Here's my page that has the clip info (and some pretty pictures) that may help. Doesn't help finding a used set for sale, though! Sorry. Prius Clip Racks
