Replacement "S" specification steering arm for all Mk2on Minis. Mk1 Minis used an arm with a differemnnt angle in conjuntion with longer rack, both of which are no longer available. These were originally fitted to "S" models and are thicker and stronger than the standard types.
 
If you are replacing the steering rack on your Mk1 Mini you will need new steering arms. This is the right hand side, see BTA895 for left hand.
