Copy of the GFC 500 STC for Mooney?

[ArrowBerry]

Does anyone have, or know where you can get, a copy of the GFC 500 STC for an M20E? I'm looking for the part numbers for the servos and components to build the autopilot so that I can price it out... it has been a very unproductive online search thus far. Basically I work for a company who is a Garmin dealer, and I've ordered Garmin products for our Mooney from them in the past. Garmin, however, seems very secretive about the STC and part numbers for the autopilot. Other items are easily found online, even through their own website. 

I know that I can "contact my Garmin dealer" and have them spend a few hours looking into it for me to get an official quote. Just looking to do as much of my own leg work and research as possible.
