Welcome from NC, I went to Ford.com and was able to download PDF's of all the manuals for my 2003. They may not go back far enough for your but these engines and trannies have been around for a long time! See what the closest they have. Also search ebay they also had printed manuals for my 2003. Good Luck! And Happy Thanksgiving!
