I did this awhile back for my own benefit, and I figured I would post it on this site and contribute what little I can. This is perfect for those without an owner's manual for their '79, or for those who just want one on their computer or a spare that they can get dirty. I just started using this sharing site and have had no problems so far, but the pdf file does take a while to download, but it's worth it! Cheers!
Just click on the image above, wait for the download link to count down and click on it. The window to save the file should open, just wait for it to load.
