Replacement Quick Grip Mount Assembly For Thule Ascent Roof Box Compatibility With Whispbar Crossbar

Question:

I have a Whispbar roof rack on my wagon and want to use my Thule Ascent cargo box on it. The boxs four clamps extend around the Whispbar bars and engage the undersides of the bars. However the boxs cradles dont sit fully on the top of the bars. These cradles are too narrow for the wide Whispbar bars. My question is... Is there a replacement cradle that I can purchase to allow the Thule box to sit fully on the top of the Whispbar bars? Thanks

The Replacement Quick Grip Mount Assembly - Thule Ascent, Atlantis, and Force Cargo Box # TH05738 will slip easily over a Whispbar crossbar and will sit on top of the boars without issue. I've attached a picture to assist.
