The best manuals for these trucks are the factory repair manuals. At some point they came up with a factory overhaul manual and took some of the more detailed and less used instructions out of the repair manual to go in the overhaul manual.There is also a factory assembly manual, which was put together with drawings showing the factory where and how to install parts, wiring, brake lines and such.
I have all three manuals for my 69, also have the two available for my 52. Also, for the 69, I have the repair and overhaul manual on CD, it allows me to print the pages I need in the shop, which helps keep the books clean.
If you don't have a local vendor to buy the manuals from, go to one of the vendors in the links sections.
