Arb Sahara from an f-series is what michael from expo vans used. All the pic links are dead but maybe you could use the same brackets??
"understeer is when you hit the wall with the front of your car, oversteer is when you hit the wall with the rear of your car, horsepower is how hard your car hits the wall, and torque is how far your car moves the wall."
Good luck, please start a thread and report back on how it works out, I would possibly be interested in that route in the future. It seems like it might take some modifying of the bumper if its similar to the ARB Sahara that MG did, with the older style van like I have he had to cut it back a bit if I recall correctly.
