Working purely on guess work here !!
I assumed, that area of the drivers footwell had that protective section placed because of the risk of the cluch lever entering the foot area in the event of an accident .... Probably also stiffens that general area where the pedal box is mounted
I used a piece of 1.6mm Zintec sheet that I had kicking about for the plate.
Going to put some prop catchers in the tunnel that's for sure
