This is the kit that allows you to delete your rear seat and replace it with 2 formed fiber-glass inserts so you can have a smooth look and lose the weight of the rear seat and/or add audio and nitrous. I was going to use it for SEMA but ran out of time. The kit is covered in dark gray carpet but it can be removed for your choice of carpet color. The kit bolts to the hinges of the rear seat so you can still fold the back down if you wish. The kit is very basic and was designed to let the installer decide on how it would be mounted in regards to folding or staying upright. I am asking $50/OBO (sorry...no NX bottle with it) [/b]
