Think the BBK, or any of the variety of late Mustang aftermarket clutch quadrant/cable setups with firewall adjuster makes a smoother, and more durable setup than the MII. Using Centerforce clutch on 351W. Was concerned with pedal effort. Can depress clutch with my hand. Don't get Corvette truck clutch leg creeping along in traffic.
There might be a slight amount of mechanical advantage. Quadrant keeps cable at constant radius on clutch pedal. Cable is lined and relatively friction free. Do initial adjustment at clutch fork under car. Then make additional adjustments from firewall. You have to reach behind the power booster to get to it, but it turns easily. Cable slips over quadrant and engages a tang in the quadrant.
