Brake Pedal return spring: 1966 Dodge Dart GT

I am not 100% sure the brake switch has been adjusted accordingly. But I have owned the car for the last 15 or so years and the switch seemed to be adjusted ok until the spring broke. I could just adjust the switch but if there was a spring in there I feel like leaving it out and adjusting the switch is not the right fix. I didn't think to check mcmaster car. I have bought from them before. The hardest part is searching on their site and not being able to hand the part to see its relative size. Thanks for that tip. I will try it.
