The reason the stock 1:25 MPC Plymouth Duster model is hard to find is because it morphed into a Dart Sport. MPC made a 1:25 plastic Plymouth Duster model until the 1975 model year. In 1976, the model was modified into a 1976 Dart Sport. The reason was because MPC came out with a 1976 Plymouth Volare model, so the 1975 Plymouth became a 1976 Dodge. Polar Lights sells a re-pop of the 1976 Dart Sport under the MPC brand.
