VOSA Rules for disco pick up.

HI guys, im looking for the rules and regs for turning my standard disco1 body into a 2 seater pick up. I love my disco so dont want to change it, but i need to be able to use it for work and the current body set up is just no use. I DO NOT WANT TO BOB TAIL HER! Just turn the rear end into a pick up. i have seen a few on the facebook sites and i think this would be the best course as if not il have to get an L200. I will not get a defender as I used them while in the army and i have never liked them.

any help would be great.

cheers Rob
