Do Shock Service Manuals Exist?

I'm just wondering if there is such thing as a service manual for shocks available.

I fancy myself an ok DIY mechanic. I'm certainly not afraid to rip into anything sitting around here. I'd like some material specific to Fox, ACT RydeFX, etc.

How do the service techs get trained? I've searched the internet hi and low, looking for material related to rebuilding shocks and I can't seem to find anything. There's got to be some info out there somewhere, huh?

I'm hoping someone can give me some direction.
