I've been searching the forum for a couple days, and time is getting short. I'm going on a trip next weekend (Columbus Day weekend) and I need some extra cargo space! I bought an OEM roof rack 2 days ago, and I found a Thule Cascade cargo box for cheap. I'll be picking it up this Sunday.

I need to know if this Thule box will attach to the OEM rack and if there is any extra needed hardware to adapt it. I only have a week until we leave, so time is of the essence if I need to order anything else.

I'm sorry is this has been asked 10x before. I've only found information about the Thule Aero stuff while searching this forum, not the Cascade. It's 6ft long.
