1930 Model A Sport Coupe Seat Adjustment Question

[Steverino]

Hi Everyone:
I am a gearhead (50's American Cars and early Honda Motorcycles) but I need some help with my Dad's recently purchased Model A. It's a Sport Coupe as noted above. He lives a couple hundred miles from me so i can't see the car in person. He says he can't move the seat back far enough for his long legs. He says there is a package tray type of cover or fiberboard piece that the top of the backrest bumps into when he trys to slide the seat back. Even though he is 86 years old, he is new to the hobby and is not a gearhead like me. The last time he had a model a was when they were only a few years old. Can this piece that is blocking the seat back be popped out? Thank you for your help.
