Still a problem
You can convert those PDF "image" files with the right software, as others have said above. I have up-to-date OmniPage software, and I have done it.
However, you are going to have some major cleanup to do afterward.
What happens is that the PDF pages get converted to Word, but the paragraph styles are really crazy. It will all look about the same as the original (if you are lucky), but you will have strange things like unexpected character spacing in the style of a paragraph.
I have always had to select the paragraphs and apply a new style to them, just to get rid of all the bizarre formatting elements.
