Don't try to get any wheels until you get the body. Then you will also have to determine what tires you want and get the specs for the tread and section width. Back spacing, wheel width and tire section width will all come into play to determine where the tire will set in relation to the body. Then if you have a solid rear axle do you have bump stops to keep the tires from rubbing the body on a hard bump. If not then you may have to move them in if you have the room, or go to a smaller wheel and tire. I recommend you mount the body, ensuring that it reasonable centered by the wheel lips and the same height side to side. Then put a level down from the wheel lips and measure to the wheel mounting points on the front and back. Once you have those measurements you can lay it all out on paper. Remember back spacing is the the rim mounting surface to the outside of the wheel lip, which is usually a 1/2". So a 10" wheel is 11" outside to outside. Take your time and get it right. Wheels and tires as you know are expensive.
