Brake help

[Bigd426]

So im not sure what to search for, but i want a wilwood master cylinder ( looks cool) but not sure to run with or with out a booster. If with out a booster how does it mount to the firewall? What else am i missing? Ive read about pedal ratio but dont understand what bore size is for what? I would like no booster because it looks cleaner. Also my truck has a complete stock 1966 brake system, 4 wheel drum, singles master cylinder and no power/booster. Can i install the master cylinder and run drums for now then convert to disc later with the same wilwood M/C ?

Not sure if this should go here the suspension fourm
