Go to a dealer and ask for new parts, see what they cost. It is not 1977. All parts cost.
And funny thing my 1973 Dart won best interior few shows. Everything fits as should. I should do a thread about it.
Dart Sport or Dart swinger? You should, that would be cool. I don't know if interior parts have improved in quality since 2007, that's when I had quality issues with Dart
