call "rc car kings" http://www.rccarkings.net/ they are a local shop here I know the have a hulk body you know the one to make the monster mutt and I bet they have some other monster jam bodies somewhere. It is worth a shot plus they have a 1-800 number so the call is free any how.
I've been trying to find that body for ages now. I even wrote to Parma and they told me that there is a chance that the Predator body along with the Goldberg and Bulldozer bodies will be re-released for the winter but there were no firm plans as of yet :tmb
