Brake pedal height

[dutch]

I'm working on a 65 Commando V8 Barracuda 4 speed car that came with power drum brakes. I installed the disc brakes, master cylinder and proportional valve from a Duster. I have had no problems with this setup, done this probably 15 years ago but its always bugged me that the brake pedal is a lot lower than the clutch pedal and looks odd so close to the floor. The brake pedal measures 4.25 inches and the clutch measures 6.5 inches from the floor to the top of rubber pad. Maybe I have the wrong length pedal rod from the clutch pedal to the torque shaft, thanks for any thoughts on this matter.
