Hello, I have a 1966 Dart GT. The problem I am having is that the brake lights are staying on unless I put my foot under the pedal. I crawled under the dash and pulled out the broken spring. I took the spring to a few hardware stores and did not find any close to what I need. I then made a replica using some wire. It worked great for one summer but then got too flimsy and does not apply enough pressure to turn the lights off anymore. I am seeking advise. Should I spend some more time trying to source a replacement spring or try my hand at making a spring again?
