Any way to attatch Yakima rocket box to Allpro Pack Rack?

Hey guys,

I have an all pro bed rack that I want to attach a yakima rocket box to. The box was designed to install on the cross bars. But those bars are closer together and smaller diameter than where I can mount it on the rack. Does anyone know of a a way to mount the yakima bars on the pack rack? maybe some type of clamp application? That way I can install the bars anywhere on the rack, and this would allow me to move the bars closer together to allow the installation of the rocket box on them.

Thanks

 

bump. anyone?

 

Doesn’t Yakima make mounts to fit anything? Might mounts I believe they’re called.
