Thule/Tepui Compatibility Fix

Hey folks!

Facing down a conundrum. We bought a topper and put beef bars on top to mount a Thule/Tepui Basin Wedge to it. Unfortunately, the mounts that Thule has available don’t fit in the narrow gap under the beef bars. Does anyone know of any solutions to mount this? Taller beef bar mounts? Other mounting solutions? Sell it all and just get the full camper solution?

Let me know!
