Also removed the third seat. Very easy.
Before disconnecting the power connector, raise the back some to access two cross bolts that hold the 40/60 together horizontally. Then lower using the power and disconnect. There is a third bolt (13mm) on the rear of the 40/60 split. Seven main bolts are 15MM and need to be replaced as the holes are open to the exterior.
I’ll fit some carpet padding or closed cell padding into the voids, then cover it all with some indoor/outdoor black carpet from Menards @ $0.49 per square foot. Comes in six foot width… so will need a 4X6 foot piece and can probably tuck it under the side trim. Cargo floor is exactly four feet wide, and need about 4'-6" to tuck under the rear trim to just behind the second row and tuck under the carpet there.
