I moved my radiator forward and recessed the firewall. I have more room then I needed, but at least the firewall stays a cooler now. I also set my engine a little high so I had to hump up the floor board to clear the automatic transmission. If I was doing it again, I would keep the floor as is and set the engine -trans just low enough to clear and as far back as I could.
You find the room in the cab is quite small, so any that you can keep, keep it! With a hump in the floor, the throttle pedal is a little farther to the left then I wanted, so it takes some getting used to when driving.
