I'm working on a 1974 1600 loadstar truck with a 345 engine,4 speed manual transmission,2 wheel drive. One of the brake lights won't work(have changed all bulbs checked the wiring and brake pedal switch) and have narrowed it down to the blinker switch (part # 435591-c91) but I can't find a replacement with that #. Is there any chance of finding a new one?
