I can't find any PDF owner's manuals for my 1983 K10 or any similar year, so I scanned my owner's manual. I find it handy to have an electronic copy I can reference.
I have two versions. The first is a PDF at the original scanned resolution which is a bit clearer. The second version is searchable, but the OCR tool in Acrobat reduces the page resolution so the pages aren't quite as clear. Take your pick.
