Hard Cargo Carrier Roof Rack Problem
 

I recently got the card corgo carrier roof rack (torpedo style) but not sure how to attach it to the utility bars. No instructions were included.

I think I may be missin a part. Has anyone done this before?

Just a single bolt with a square end sticks out of bottom in four locations.

Does something wrap around the bar? Or do I have to drill?

Any help greatly appreciated.
Thanks.

take the rubber cover off of the tops of the crossbows. slide the little squares into the groove from the end and bolt that sucker down!
