So maybe I am missing something.... lol 1964 Plymouth Valiant Parts | SF150 | 1960-65 Mopar A-Body / B-Body Front Bucket Seat Foam | Classic Industries is listed for 60-65 a body bucket seats. However, based on the picture, the middle of the seat is lower than the sides. Mine seem to be flat. so I am not sure that these will work. the other option is that these are not original seats. This car was a project car for the previous owner and so the seats might not be original and if they are not, then I am not sure what car they came from.
