I'm in the process of the same thing. I bought a used Nitro Hawk off of ebay. I cleaned it up real good...added bearings, rebuilt the shocks, new tires and added a new Pro .15. My Nitro Hawk is almost done it just needs the break set up and linkages. Anyways, the Traxxas white dish wheels are still available if your wanting to keep it as original as possible.

Heres a couple of pics of mine...
