I have never taken a front seat apart, but am about to dive into it.
Even though the seat back adjustor bolt is extended, the Pass seat leans back excessively. I run out of adjustor before seat back is in a "normal" position. And then, seat back is really spongey. Am looking at the seat back adjustor plate that has the 2 screws connecting it to the seat frame. Really looks like the plate is sunk into the seat frame quite a bit. From pictures I have seen, the tube that comprises the seat base frame appears to be on same plane. However, this tube seems to have a "dip" in rear which appears to allow the plate to be at a deep angle. Anyone ever have this type problem and other than replacing the seat base frame, what did you do to fix it?
