The factory manual is the Helms manual. It is like a thousand pages long so it would be a long download that uses tons of bandwidth. A while back someone had a .pdf file of the catalog online but I forget who it was.
edit 2: I just found a copy of the 86 manual for anyone that cares. It can be found here http://cs.pontiac-club.com/..._download.php?id=270 Its not in english, but you just need to click the button that says Stáhnout. You'll have to register first, but after that you can just download it.
