Ever work on a Jeep bobtail with the Nissan forklift diesel? First the AGE guys figured out they could remove the steering stops on the front axle to turn sharper. So much flex that they'd get cracks cross the back of the cab from body mount to body mount; TCTO to inspect and repair, plus reinstall the stops and weld them in place. Then they found out that the Jeeps didn't have a super-high rear axle ratio, just a transfer case with no shifter and a plate to lock it in low range. With one 3/8" bolt holding the plate on. Pull the bolt off, use the plate to shift it into "high" and they'd run 50+ mph. They rolled one on midnights at Mildenhall...
