Dart wagon patch panels for rear wheel arches

FWIW I used Valiant/Barracuda lower quarter panel patches from Layson’s on my 65 dart. I can’t remember if they weee shorter/longer than the wagon’s lower quarters, but whichever we modified the patches to make them work
Thanks for the info. One restoration shop I spoke with suggested starting from front quarters to adapt to the rear, and while the Dart's are somewhat flattened on top, the Valiant's are more round. That's pretty much my backup plan if I can't source any solid panels from a donor wagon.
