Regardless of the copyright, all you have to do is redraw the parts, make it look a little different, and you got it. What ever you do, do not reference it back to the document it was taken from. All you have to do is make a slight change to the die filer and it is considered different and does not meet the guidelines of copyright materials.
Just saying. I've done this many times in the stuff I do for a living. As long as it is not in the same format as the original document, there's no way the original owner can come back and bring legal action against you.
