So I'm building a single seater with no parts newer than 1950. I'm needing to start figuring out pedal location so I need to get a master cylinder. I'm using 40 ford front and rear brakes so I could use the 40 master cylinder but I'm thinking even though its not older than 1950 I should use a duel res. master. Whats your thoughts, Keep it period correct or make a concession for safety and run a duel.
