As stated above, plenty of different pdf copies available here (in resources section) and on the web. pdf's are nice 'cuz you can print out the sections you're working on, staple, and gets all kinds of greasy fingerprints on them and never care.
You'll want the 2F engine manual
Body and Chassis manual for FJ60s (there are a couple different ones and some cover the FJ62 US-spec)
81-87 Emissions FSM
And you should REALLY REALLY consider a paid subscription ($20/year or cheaper for longer) like Silver Star etc. Allows unlimited picture posting and a bunch of other benefits. Pictures will be worth the cost for aiding in diagnosis. Plus, you won't get any of those annoying pop up ads. At the top menu bar, subscriptions are under 'Store'. Also, without MUD, there'd be a lot fewer early Cruisers on the road, I bet. This site is very worthy of the support. I know in the early days for me, it would have been a lot harder process without IH8MUD hive knowledge.
Good luck!
