I've seen one. It was a LH23M8 car. Totally rotted out even the roof. I believe it was in Minnesota by that Infamous Hemi guy who was trying to sell me a Hemi car, sent me a picture of the title but when I drove all the way out there, he didn't have it as he still owed $$ to the owners. On the Dart it was impossible to repair and the way he talked he was just going to rebody it. Illegal as hell.
You mean LS23M8B as H would be a Dart 270 and no M code Dart was ever an H. What year was this that Fred had the car? It might be the one I pictured above as it had a complete rear clip grafted on it...
