As far as the bed goes I would look in the wrecking yards or car parts.com. Gonna cost a pretty penny but if you want it you should be able to find it. The step side also came on 4x4s and prerunners so its not a 2wd only option. As far as the CVs go there is a company that does a rebuild (CV unlimited I believe) but they are pretty expensive as well. You should look into an replacement axle with a life time warranty like from autozone or some place like that. It would be cheaper in the long run.
