Just cut out the guards on the back of a Corolla (a not too good condition one) with some homemade flares, and fit 4by tyres under it. Mates old man fitted 4by tyres under his 2WD Rodeo (minus the chopping of course) and it doesn't rub, but is awesome off road, even in mud. Means you don't have the extra weight of the 4WD (also, notice 4 and $ are in the same place on your keyboard), and it'll still drift in the mud!!!
