I have recently acquired a sizeable collection of Vintage Diesel Maintenance and Service Manuals including many from Caterpillar, John Deere, New Holland, Case, International, Detroit Diesel, Cummins, and Allison Transmission as well as many passenger car/truck service manuals from manufacturers like Chevrolet, Chrysler, Ford, etc.  Please take the time to look through my other listings to see if there are other books that you may be interested in.
