master cylinder

i am building a 47 ford sedan and was wondering what type of master cylinder to use.i am wanting something i can mount on the firewall with a pedal.thanks

Disc or drum, power assist or not????

I have a 47 sedan and used a 92 fireird m/c and pedal. I also installed the rearend from the same card Here are a couple of pics wuth the m/c. And yes the hood does colse and is now on the car. Only real mod was some extra bracing for the brake assembly due to the firewall flex after removing the stock m/c and dash brace
