it wouldnt cost much to do it i dont rekon.. like for a lib one.. you would have to jsut get a front cut of whatever model you wanted.. and then sell off the motor and make some moeny back.. or even keep it and build it up..
Then strip inside the front cut and fix it up.. put a whole back on it, and get number plate, toe ball.. and connect it up for power for the front lights, so it's a trailer hehe weeeeee done!
