Dart Wagon 3rd Row Seat?

3rd row seat was an option on 60-62 Lancer and Valiant wagons. I haven't actually seen pictures of the setup, so I don't know how everything was arranged. Maybe someone can post pictures.

On '63-'66s, the gas tank and spare tire are going to be in the way. Other wagons of the era put the gas tank up against the rear fender, but then it's more exposed to rupturing in a crash. The '85 Caprice 9-passenger wagon we had when I was younger had the spare tire up against the rear fender hidden under the interior trim. To duplicate that, you'd need to fabricate some kind of well for it to sit in in the dead area inside the rear fender, some way to secure it, and some way to get it in and out.
