Since we are moving the engine back so much, we are compromising the foot well quite a bit. We plan to move the seat back 4 inches also, which will put the driver's back at the forward edge of the rear quarter window. Back a bit from stock, but not so far back it feels like a Funny Car either. We will build an interior toe board 4 inches closer to the driver so the pedals are not hanging in free air. We realized after tacking in the main hump (wheelbarrow) that we still need some extra room.
