I used the mbx4 wing kit. On the traxxas forum somebody posted a nice how to on how to mount the wing to a stock body tower. Dont hav ehte link saved anymore tho. http://www.crispycrittershobbyshop.c...cat=479&page=1

And as for a body, they dont have one for the extended truck that I know of besides the stock traxxas one so what you will have to do it mount it in the rear with the stock holes and in the front make new ones. Easiest way to do that is put a dab of paint on both the top of the front body posts and then center the body and put it down. When you lift the body off the truck you got nice little paint marks of were to put the holes.
