I'll answer myself, in case it will help someone else out there someday.
Apparently, Traxxas still makes the Nitro Sport, which is just an updated version of the Nitro Hawk. A lot of the same parts (Shocks, wheels, and a slightly revamped body) carry the same part numbers and look to be completely compatible. Not everywhere carries the Sport, or even all of its parts, but between A-Main, Tower, and Ebay I should be able to piece together all of the parts that I need to make the truck look fresh and new again.
Thanks, Paul!
You're welcome.
