You'll need those, shims (naturally), as well as
these (lowers the center diff),
this (different front the CR to the CRT, because the CRT has the larger spur which would hit the buggy one), and a Kyosho spur, which I assume you have already. If your using Mikes mount, your gonna have to get the buggy one to lower the center diff. Now, some of this is based on the fact that its brushless, which I would assume it is...
