Gents, I've got a shit ton of GM service manuals and parts manuals and owners manuals and shit like that on PDF and just nabbed some server space to host them so they will be put up here for now. When I get it all set up I will post the squarebody ones on the square site. I think I've got this fixed now.
Please only download one file at a time, keeps down the load on the server. Just right click and save as. Let me know if there are any problems.
