Rear seat on 69 Coronet

Is the back seat the same for a 4 door and a 2 door ? I have a 4 door beater 69 coronet needing the rear seat. Someone told me that one from a 2 door will not work. I figured someone here would know if they were interchangable or not. Thanks.

The upper part may be the same but the bottoms are different.Not sure about the top though.Someone on here should know for sure.

Thanks for the input !

I put a 4 door seat in my 65.Cant tell that its from a 4 door.Rocky
