I am only aware of three bodies for the f104, they are all from Tamiya... the one it comes with is supposed to be the mclaren that won the last championship, there is a new one coming out that is the light weight version of the same the third one of course is the ferrari f60..
also i think there are two more coming out from vintage.. the lotus and the wolf
some good places i think worth looking at are trg-rc.com, they have links to zen f104 parts.. they might make bodies as well but not sure...
