'69 Cuda rear seat

[gynopski]

I'm presently working on a'69 Cuda Fastback for a guy that bought it totally disassembled.He bought it with the seats already reupholstered,I'm just putting the interior in it now and I notice the rear seat cushion is about 9inches shorter than the width between the inner 1/4 panels.I am wondering if this is the correct seat bottom.It looks funny with a 4 1/2" gap on each side,if it is correct is there something that is supposed to fill the gap.If someone could post a picture of this I would appreciate this.
Thanks

Yeah, Thats right but somone ordered the wrong carpet set for the car. Fastback Barracuda is all by its self.

There should be covers for the seat hinges also.
