INNER rocker panel piece needed Dart Sport

It may come to that but I would really like to have a factory piece. If I had a sheet metal brake it wouldn't be too hard. It actually has several bends and different angles. Needs to be fairly precise. My Goodmark quarter skin doesn't have the bottom lip that fastens to the rocker lip so I need to weld it to the bottom of this inner rocker piece.
I don't know if a Swinger has the same shape part but I'm about to take a Sawzall to some of my parts cars and find out. I was hoping someone from a dry area was cutting up a Duster, Demon, or Dart Sport for parts. I've seen them advertised before but it's been awhile. I have over a dozen parts cars but not what I need. :angry7:
