Hello there, I hope you are all well! I live in Dublin and drive a 1977 Honda Civic as my every day car (I mention this as everyone asks). My indicator switch went a year ago and I had an electrical guy fix it, but now it has gone again and I need to replace it or else stick buttons on the dash. I would really like to keep it the way it is! If anyone could help source one or give me an idea of where I could, I would be really grateful! It is my baby!
