3d panel stuff (gtx-328, af3400)

[flyvans.com]

hi,

i'm looking for either accurate 3d models or dimensional drawings of

a Garmin GTX-328 transponder (haven't got the install manual yet and none found on the net)
or could anyone confirm that it's the exact same tray as for a GTX-330, for which i did find the documentation?

and of the advanced flight systems AF3400. The official documentation, although perfect for the cutout, doesn't cover the rear. It does it only for the 3500. Maybe someone else has been there. We're trying to determine the maximum up and left / right positions in a RV-7A tipup panel.

the 3d models found in the accuracy avionics 3d file, seem not deep enough to cover the back realistically.

thanks for any files, hints, pictures or dimensions.


kind regards,

bernie
