does the thule hang two surf carrier need a rack to attach to?

It WON'T install directly to the factory installed FJ Cruiser rack, just FYI. You have to buy a whole new $300 system just to get these to work. Fail...

I got this for my '02 Pathfinder. I don't have a Thule rack, just my factory racks. My factory racks are really wide. The Hang Two bases fit, however, the hardware wasn't long enough. I went to the local hardware store and got some longer screws, washers and bolts. They worked great. Remember tho, Thule is metric. So if you need longer hardware make sure you get the exact width and thread otherwise you're screwed (no pun intended). Peace.
