I have the Gregory’s, Haynes, and Ellery’s manuals that cover my year 2000 HZJ78 Troopy, and do not rate them at all. They are not specific enough for the 78/79 series, as the Gregory’s and Haynes both cover 100/105 as well as 78/79 from 1998 to 2004, and the Ellery’s covers the 100/105 and 80 as well as the 70 series from 1990 to 2007.
I also have all the Toyota factory manuals, that I know of, which cover the first of the 78/79 series (as well as earlier 70 series models), I prefer them to the manuals mentioned above.
These are what I have, the supplements cover changes since the earlier model/manual, so if it is not in the supplement then you refer to the earlier manual…

The first Repair Manual for Chassis & Body (RM183E) is available on the net to download, as is the first Engine Repair Manual (RM172E). I have not seen any of the others available to download, but they may be out there somewhere.
I have scanned in a few pages from these manuals to help people out with problems on various forums, they can give an idea of what the factory manuals are like…

I have also scanned some of the first EWD (EWD168F) into a PDF file (8MB) that I could email to you, but only those pages that relate to the RHD/1HZ heavy duty models (though the actual wiring diagrams cover all the heavy duty models, I didn't scan any of the light duty diagrams).
