Hey folks, I’m helping my father out on his ‘53 project that we started a while back. We are having trouble finding or figuring out what goes in this weird hole under the seat in the cab. I found a single picture of the hole in the assembly manual but no reference as to what goes there.

Pictures are attached. Bottom of the cab, in the middle of where the seat is.
Note: last picture is of a new floor pan, without the mysterious hole.

Replacement floor pans do not have this hole
