Does anyone find a surfboard carrier that can fit on factory crossbar?!

 

i'm assuming you're talking about the factory cross bar on a WRX wagon. i have a yakima rack that works really well (it's on my sedan), and i think that they make a mounting system that will fit the factory crossbars on a wagon. you'd probably have to mount one of their cross bars on top, using the mounting kit they sell. if not, you could always go the soft rack route, i think Da Kine makes one. check out http://www.yakima.com to see what fits your wagon.
