snowboard

So I wanna go riding with friends and take the E cause of the AWD and I was wondering if it's possible to put two snowboard racks on the roof do I can hold 4 boards up there.

Hi... I've searched throughout the entire forum and can't seem to find an answer. I have 2007 SC with factory roof rack. I just installed a Thule 91725 Snowboard attachment but my snowboard doesn't fit between the bars? Does anyone know how to correct? Or do I need something different?
