if you dont mind updating the thread when you rear delete id be interested, as i did the same, was going to make something out of standard automotive carpet but if they sell it by the yard i may go that route too!
Suppose you have this all figured out by now, anyway finely I got this sorted out.
Dantes has now made me a carpet less jute backing and will add a yard to cover for the rear seat delete. Roll is 6 foot wide, and that´s wide enough...
