I've attached a couple pics to show how my Trutrak Vizion Autopilot is going into the World VFR Panel. So far, with a minor modification behind the panel and a cutout in the bottom of the panel it's working out real well.
The AP head fits just fine in under the 796 slot. Mitch is working on a new overlay. When you get the World VFR panel there's 2 holes at the top of this area that actually line up with the AP template so locating the cutout is really quite straightforward.
Notice the magic blue button left of the controller....Vizion's wings level feature.

The Com and Transponder hardware boxes have to be moved out to allow the AP controller to slide in between. Once again, pretty easily done. Just remove the bottom fasteners of each box clamp. Swing it out leaving about 1/8" clearnace between adjacent instruments and match drill a new hole into the backer plate, using the existing hole in the clamp plate.
