Jan, as far as I know, there is no P/E set available to this truck. In fact, detail information is a little scarce, too. I did find that http://olddodges.com/ had some good information as does http://public.fotki....rochures/dodge/
For the "700" logo on the side of the cab, I used some Bare Metal Foil & some black paint.
Good luck with your project, and I'm looking forward to some progress pictures.
