PDF copies of 67-72 GM truck Service Manuals

[hatzie]

I usually post on the 73-87 side but I have collected copies of most of the 67-72 light truck service literature.
PDF scans of 1967-1972 GMC and Chevrolet Light 10-30, Medium 40-60, and Heavy 70-90 Truck Service Manuals from my library.
The links are to the PDF files on MediaFire.
I personally like paper manuals that I can hold in my hands. These PDF files are a good compromise till you can buy a hardcopy. I made them searchable allowing me to find the pages I'm looking for and slip in bookmarks so I can find them again in the shop.
The paper manuals aren't expensive and are well worth buying used when they come up.

I will eventually scan and link all the manuals on this list. If it's not listed I don't own it.

Wiring manuals cover all GMC light through heavy models in the year listed.
My scanner only handles 12"x32" pages. The longer fold-out pages in the 68-72 wiring manuals have been scanned from both ends and stitched to the full original length.

68 wiring is up. 72 manuals are on loan. Waiting on the printers cute little girl to remove the binding glue from the rest with their guillotine. Then I can scan the rest of these manuals and put most of the paper away in a mouse-proof container.
