I'm looking for a manual or drawings that show how all the body panels and parts join.. does anything like this exist? Which panels or parts go under another, etc.
There are probably manuals that show individual parts, but not how they attach. If you're planning to remove body panels, take photos and make notes
as to how they were attached. Replacement panels should have flanges that will correspond to how they are joined. I parted out a 62 Dart that somebody
had put on new 1/4 panels at some point. The rear body panel over lapped on one side and was underneath on the other side. I don't know which was
correct.
