I am almost positive that Mike is (or at least in the pic BOR posted) using a rc10t4 body.

This is a rc10gt, look how far back the bumps for the shock towers are.

This is a rc10t4, the bumps for the shock towers are much closer for the centerline of the body.

I now use a proline Traxxas rustler CP body on my crt.5ext, it fits really good. (I have also changed all my electronics from the pic)
