40 deluxe seats

[goshencars]

I need some advice on the seat covers for my 40 deluxe. The front seat only has two sets of ribs sewn in but the Ford book says there should be three. I assume the third set is in the bottom seat only because of the sedan back is split. My back seat has no ribs at all. I don't know if these are original seats to the car. Also I think the back seat should have a strip of carpet on the bottom face. I don't know how wide through. Maybe the same height as the door panels. Any confirmation and correct photos would be appreciated. Thanks
