Mini tub fastback pics anyone?

It would help me some if my back seat was in the car when I got it.But it looks like the only part of the seat that is between the factory tubs is the seat back at the bottom,right?So has anyone mini tubbed their car and just moved the seat foward a bit instead of narrowing it?

I don't see anything that seems apparent that has been done to the rear seat in the pics of the red cuda above.
