Installing rubber floor 53 F100

[Fran loves Fords]

I am installing a new rubber floor in my 53 F100. I am having a difficult time figuring out how to remove the gas pedal so I can allow for the cutout for the pedal? any suggestions?

It also looks like I need to remove the steering column to allow for the floor cutouts as well. any suggestions on the easiest way to do this?

I have a 239 flathead with 3 speed on the column.

Thx
