If I were doing it, I would cut the firewall and build a dog house to allow the engine/transmission to be moved to the rear far enough to be able to leave the radiator in the stock position. Nobody rides in the middle of the bench seat anyway. The front seat is narrow enough to reach the ole lady as well.
