You want a user manual for the basic stuff, EMERS for the j60, and illustrated parts listings are also useful, you need the cvrt common items one and there is also one for the spartan variant...there is also an electrical systems manual but the one i have is for scorpion which does for most stuff, not sure if there is a spartan one..
Mark at vintage mv manuals/green machine (per your link above) can do all of these and i have always found him very reliable...
To put it in perspective a mate has a challenger one and picked up a set of manuals for it earlier this year...something like 40 volumes and 6 foot long...!
