I finished drilling the rear wall to the upper cross member and adjacent aluminum panels.
Since I’m moving the emergency brake, I needed to make a cover for the old opening. The kit comes with two different front panels for the driver’s side foot box, so I took the unneeded one and cut a piece off the bottom to cover the hole. I’ll match drill this to the existing holes that tie the transmission side panel to the chassis and add some additional holes around the perimeter.
