I just made a post in the Misc Stovebolt Stuff section listing the first set of GMC manuals/books I am selling.

I still have my 53 GMC Firetruck and just sold my 54 GMC COE and thus had collected a lot of manuals/books (over 100).

My passion has moved to fidning a pre 1920 GMC so I am selling all of my 40's-60's books/manuals.

Here is the link to the list thus far:

If there is something you are looking to find which is not listed let me know and I will check my manulas. - Bob
