Back seat differences

[hosehead]

My 66 dart has a back seat that seems too short on the bottom part. It’s not original to the car.
Do any of you know if a four door rear seat bottom is shorter? I am thinking this rear seat is from a four door. Here is a pic.

Here is a pic of the back seat from an original 66 dart. The seat bottom sticks out much further.
I want to make sure I have the correct seat before I go to the upholstery shop.
Thanks guys.

A friends back seat. Also original to the car.

I believe wagons use a different rear seat base; a parts book would verify this.

The Valiant has a shorter wheel base than the Dart and the Valiant seat bottom is shorter .

Dart seat is 22" front to back on the cushion and 19" front to back at the base .
