Just in case anyone is still looking for the Ford Service Manual, I found the PC program for 2003 Mustangs, not sure if it will work for any other year models.
I uploaded it to my Dropbox and you can download it here:
1. Unzip the file to C:\TSO
2. Run the setup.exe and install it into C:\TSO
3. Exit out of the installer without running the program when finished
4. Edit the tsobrowser.ini file in C:\TSO and modify the 03Must line to say this: 03Must=1~1~C:\TSO\~stock\home.htm~2003 Mustang~October 2002
5. Then run the program and it should work fine.
Note: I had to install Adobe Acrobat before installing the Service Manual in order to get it to work, and also run the Service Manual program in Windows XP Service Pack 2 Compatibilty Mode in order to get it to work correctly on my Windows 7 laptop.
