Brake pedal

This might be premature but my question is do I need a diffrent brake pedal? Heres the situation. "70 duster" , all my hardware came from a scamp. I am converting manual front drum SBP to disk, K-H SBP. I got everything (Some of which I know I didnt need but was able to grab it anyways) which includes upper/lower control arms, disc's hubs, proportioning valve, lines, power booster / master cylinder and all the hardware which mounts to the firewall including the bracket which attaches to the brake pedal. Will this bracket mount to my existing manual pedal or do I need a diffrent pedal assembly also? It looks diffrent to me.
