is it possible to romove the seatback from the front seats?
I gave the top of it a pull, and two tabs came free allowing me to pry it back some. But I cannot completely remove it. It seems to be securly attaches with something other than pressure clips but I cant find any screws or anything.

Anybody done this?

 

I figured it out.

2 8mm bolts at the bottom and behind of the seatback. These are very hard to access.
2 pressure clips at the top and 2 hooks in the middle on the sides.
