v6 Back seat interior question.

[Tyler Woodall]

Hey guys! I've got a 2002 stang that I love to death. I've fixed her up for the past 6 months and I've finally gotten all the exterior and the exhaust finished, and the last thing i need to do to get her back in her prime is replace a piece of interior over the back seats. The piece goes behind the seats and is as long as the car is wide. Can anyone get me a part number or name? thanks!
