Sorry this was overlooked. The disc brake booster should fit, even though the Cougar is a Bendix and the Torino used a Midland booster. The axle will swap over; the widths aren't exactly the same, but you have a pretty good amount of wheelwell rooms. The steering box won't swap, it's a different system, but I believe the disc brakes will as long as you swap the spindles.
