Where are these things available?

You can get frame rails from Paul or contact Rick at gardentrucking.com. I would suggest calling him because he can tell you more about them but his rails are perfect. There is absolutely no modification required to any of the stock Tamiya parts to get them to fit and they come very well packaged. I believe he just sells them in 36" lengths and you cut them to your specific needs.

As for tires, RC4WD has some really good tires and the compound is great as well. You can also find some integy ones on Towerhobbies but I have no experience with them or haven't heard anything about them yet.

Good luck and hope that helps you out some.
