I looked at some photos sent to me by a fellow iboats member who happens to own the same boat as I do. He sent me a lot of great photos of the interior. Through them I saw that the bottom seat panel extends to the gunwales. Again, I used what was in the boat as a pattern, and it turned out too short. At least the frame was correct, so I just cut a new front panel. I also rearranged the seat support top frame so I can get my life vest pack in. There should be enough support here.
