Many years ago and actually buying Mopar service manuals, I bought from a seller named Irv Bishko. He was very good and sold an excellent product. I have since noticed him as an ebay seller. I don't know if he still has an excellent source for the original manuals or if all this time in business has pushed him to reproductions but if he tells you it is the real deal, my comment on his quality service stands as a high recommendation from me if that means anything to anyone.
