I cant tell you exactly where to cut the body out at but I can tell you what holes I have my body mounted on. In the front Im in the 5th hole up from the bottom and in the rear Im in the lowest hole....this is with the little plastic rocker pices on the stock body posts. I mounted the body on the car then ran a sharpie laid down on my pit board around the body after it was mounted to get a cut line. Then ran the body and trimed as needed. Hope this helps.
