I did the same as this fellow 
http://forums.genvibe.com/zerothread?id ... =2387#2387 I covered the entire cargo area as well.  I velcroed the carpet to the back of the seats, a fabric store could set you up with sticky back velcro but you may need better glue, I did.  Took me about 1/2 an hour.You could cut the carpet in three strips in the cargo area and four on back of the seats to leave room for the tie down channels.Have fun
