Your going to want to build a brace for the rear body mount. Something like this.
I used a turnbuckle. Made a small aluminum plate and mounted it to the shock mount screws, connected the turnbuckle with a m3 screw and nut there, popped the ball out of the other end and used an m4 screw on the rear body mount where the exhaust bracket would go on a nitro. It tdoesn't take to many flips to break the rear body mount and an aluminum mount breaks even quicker.
