Rear Seat back with centre arm rest and load through hatch - S3 8v

[S3nutjob]

Hi,
I am looking to retro fit/ swap my 60/4O rear seat back with one that has a centre arm rest and load through hatch or a 40/20/40 split. I believe that the Sportback and saloon have the same rear seats.

my seats are the standard S3 sports seats in black nappa leather. The rear seats are immaculate and practically unused.

thanks
