Jeff, I believe that the cab is a "Bruder" adapted to the Tamiya chassis, a custom build. As far as I know the Bruder products are still available at toy stores and on e-bay. They can be purchased separately as individual vehicles or some in sets with other types of equipment and extras.

There are several threads that document the conversions on this forum. You can search to see how these were done.

I hope this helps. Have you purchased a truck yet?

Jim
