The brake booster in my 1969 Dodge Charger (318 automatic) is leaking (though, strangely, it stops leaking when you press hard on the brake pedal; I have no idea why). When I converted to front disc brakes last year, I used a '76 Volare master cylinder. Can I also use a brake booster from a '76 Volare, or any other 4-bolt Mopar booster from that era?
