Hey KnuckleDuster. I have a 1973 Dodge Dart Sport 340 a 72 Demon and a 70 Dart Swinger. The Dart Sport is a work in progress running and driving car. The Demon is a 52 K mile survivor and the 70 Dart is mostly restored. Have had the 70 for about 25 years, the 72 for about 16 years and the 73 for 6 years.
