67 Newport Disc Brake conversion rod question

Hi all, I am a new owner of a 67 newport. I am converting it to front disc brakes. I got a booster from pirate jacks and mounted it to the car. My question is about the part that connects from the brake pedal arm to the booster. It looks like a letter L. Currently, I have the new booster mounted directly to the firewall and the booster rod connected to the pedal arm. Thanks for the help
