Rhino-Rack Vortex Aero Crossbars like the # RRVA126B-2 will only fit Rhino-Rack feet. Unfortunately, since Rhino-Rack does not make feet compatible with your 2023 Toyota BZ4X the only solution is to sell your old crossbars and completely replace the roof rack. For the Thule WingBar Evo roof rack you will need the following:
-Thule WingBar Evo Crossbars # TH711320
-Evo Fixpoint Feet for Thule Evo Crossbars # TH49SC
-Fit Kit for Thule Evo Fixpoint and Edge Fixpoint Roof Rack Feet # TH74CE
