Make every effort to use the dual-circuit system, for safety reasons.
If one circuit goes out, you'll still have half of your brakes. When it
comes to brakes, the safer the better. And don't think "It'll never
happen to me...".

1. Get into the car.
2. Press firmly on the brake pedal.
3. Start the car.
4. If you feel something helping you push down on the pedal when the
motor starts running, the servo is working.
The diaphragm can rupture inside the servo. Other than that, I don't
know.

All the servo does is help you push on the pedal. It doesn't do
anything with hydraulic fluid.

I don't know; you didn't state what your existing system was. If I
assume that it's a stock '67 system, the biggest difference will be the
reduced pedal pressure required for stopping. The second biggest
difference will be the addition of one more system to fail.
