Honestly download the online '85 FSM from ttora or somewhere similar. It's way better than this link. I appreciate the link and I used it for a bit but it's really not much better than having a Chilton or Haynes. The 85 to me is better because it's an FSM, and not that much stuff changed mechanically.
Probably not something I'd like to broadcast out too far but I have an '83 FSM and don't mind scanning small bits (a page or two here and there) if people need stuff. There are probably plenty of other people on here with first gen FSM's who would do the same..
