Where to find a parts manual?

[odsteve]

Hi,
Anyone have any idea where I can find a International Harvester parts manual, MT-502 for medium duty trucks? It would have been originally published in the early 1980's and I don't know when the last publication date was. Although I'd prefer an original, I'll take a photocopy or pdf of the book if that is all I can get. Binder books has been bought out by ihpartsAmerica and they don't have one, so any suggestions, anyone?
Thank you.

These two would be top of the list.
