Hydraulic Brake Booster — Ford Bronco

Hydro-boost upgrade with 3.20 in centre-to-centre master-cylinder stud spacing and a short, near-flush master-cylinder side output pin. Compare your original unit's mounting pattern and master-cylinder output pin style against the photos before ordering. This is a specification-defined unit, not a vehicle-catalogued part, so a year-and-model lookup will not confirm it.
