Hey guys. I just checked and could not find a lever from the rear of the front seats. I looked from the front of the seats and found the lever. My drivers side does the tumble also. The cable in the seat is broken so the tab in the seatback or the lever on the back of the seat does not work for tumbling the seat forward, but the levers accessed from the front of the seats work great.

See post 29 above. It's not so much a lever on the backside as it is more of a tab near the lower outside of the seat back. Of course if your cable is broken inside, locating it won't do you much good.
