Don it looks like this is a build it yourself deal for Dynon in a RV 12. i was quite surprised when I could not find anything on the Dynon site for a 12 install. I wonder why that is? Lots of 12s out there now.
Actually a standard build of an RV-12 has all of the mounting brackets for servo installation, and wiring installed during the build so installation sometime later is about as easy as it could be (other than needing to access a location in the tailcone for the roll servo).
Scott .... Correct me if I'm wrong but I think I remember the Autopilot servo mounting brackets were a separate install on earlier versions of the RV-12 and came with the AP kit. What you said is true now days and has been for a few years now. Unless I'm confused, the changeover happened around the time I ordered the AP kit early to have the brackets so they could be installed during the fuselage build ... only to find out they were now being included in the fuselage kit.
I think Don started his kit prior to mine so likely did not receive the AP servo mounting brackets with his fuselage kit.
