I am in the process of downloading a RHD version of the workshop manual. this is almost the same that is found in this thread http://vehicross.info/forums/showthread.php?t=14757 but also contains a RHD version as well.
the overall file size is 242 MB and I purchased though http://www.datamanuals.net/isuzucomp_99_01.htm. (as you can see the pdf has other car manuals as well)
I will edit this post when I get time to compare the download to what is available on this site.
Datamanuals clams that it has the RHD drive version on the pdf. will let you all know how it goes.
If it is what I am hoping then I am happy to burn a copy to cd and mail it around or if the admin are happy to host the RHD version on this site then its all vegemite side up!
