PDF copies of 67-72 GM truck Service Manuals
 

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.
