Does anyone know or has anyone attempted to remove the rear seat back on an A5? I only want to remove the split back portion behind the driver side so basically I have the 60/40 split and I want to remove the 40 side. I already removed the center latch hold down which allows you to lift the seats and disengage the center pivot point but I cannot slide the seat out of its holder in the frame of the car Where the seatbelt and armrest is...

Thanks in advance...
