Fold down seat question

What have you learned from the FSM? After another look that seat back if 69 already had the rear piece that faces the back pulled in the pic. It is hard to see where the side trim mounted at the pivot bar point or should mount.
I learned it was to big to download on my phone lol! Haven't had time use the laptop yet, but I already figured I'll engineer something anyway and keep my eyes open at Carlisle
