Choose the correct model and attachment
The complete 910021-00 kit contains a crossbar, appropriate quick-disconnect brackets, base pins and mounting hardware. Roadmaster 222 is the car-side bracket half-set, not a complete crossbar or both halves of the quick-disconnect mechanism. These components are for compatible crossbar-style baseplates, not Roadmaster direct-connect installations.
