Theres lots of links to fsm’s for 10-13’s floating around. Mechanically they’re 99% the same so if you’re looking for it for wrenching you can certainly get by with one of those. The main difference is going to be the face lift body stuff and interior electronics and I’d just start cutting the former and never touch the later : )
@r2m started this handy thread -
GX 460 Manuals - https://forum.ih8mud.com/threads/gx-460-manuals.1129713/ and
@Acrad posted links to some good club lex resources.
I don’t remember where I got them (probably through the links above) but I have a digital copy and a pdf of the 10-13 version. I don’t want to post them but if you pm me I’ll send you a temp link. And then burn this thread. If you’re just looking to do suspension work, fluids and basic maint, the early year manuals should get you by.
