The up to 2010 in whatever number revision is available from many sites on the net, or for about $5 on ebay. What came after that I have no idea but given these revisions can pretty much be done by any dodgy ebay seller then uploaded to an internet server the revisions may not actually mean much even with a picture of the newer model on the cover.
I did some searching here and some googling and downloaded an extensive workshop manual with a rar extension
After unzipping the file I now have the fully blown manual on my computer
It was free
It's just great a good reference for all the Navara D40
The file is called AU D40.RAR - if you click on the "Download" button it will come up with a page warning you about critical registry errors that need urgent attention. Do NOT click on that. Just save the file, then scan it.
Worst case: PM me your email address and I'll email you the archive (it's clean and thoroughly used, I'm sure the PDF pages are nearly all dog-eared by now!).
I've zipped the files into two parts since Gmail doesn't like more than 25Mb attachments. Currently in the process of uploading #1, #2 won't be far behind.
