Cargo boxes for factory aero bars?

[jordanair45]

Does anyone know which cargo boxes fit on the factory aero bars?

Looking at the yakima rocketbox pro 12.

Seems like it should just snap right on?

Yakima Skybox is about 8 yrs old and fits the bigger aero cross bars of the Tesla rack
I also called Yakima about other carriers I own and they were helpful after requesting pictures of the rack and the other carriers
