Nice Josh!
The model kit had two holes in the front of the bumper where the bottom of the car would mount. What I did is cut the frnt part of the chassis part and glue it to the car. Now I'm not talking about the frnt of the xmod chassis, but the frnt of the model chassis. After that I just mounted a front clip port from a supra bumper and positioned it till I likeed the stance. It was very simple.
I will still put up a pic to show you exactly. When you get your model, if you need any help mounting the body just pm with any questions. I'll be more than happy to help out a fellow xmoder.
