Blue Mountain Remove from Panel

We are upgrading the panel in our RV-6. At first glance, we can't figure out how to remove the 2 Blue Mountain EFIS/Light G3 Lite and G4. Any suggestions? They are not flush mounted, but removing the 2 Allen screws from the top and bottom did not seem to loosen anything. Thanks for any help.
 
Pictures?

Any pictures of your particular installation?
Pictures can help a lot to give you some orientation. Some BMA EFIS are secured from a nut (4 actually) in “the back of screen”, not the Allen screw.
Good luck.
 
Remove Blue Mountain EFIS

These are the two Blue Mountain EFIS units - G3 and G4 Lite - we are trying to remove. We cannot figure out how they were/are attached to the panel. Thanks for any help.
 
Poking around on the internet I found this photo of the backside of the Blue Mountain EFIS. My guess is that there are 4 nuts on the backside of the panel holding the instrument in place.

Thank you very much for the photo. We will have another look at the back side of the panel next time we go to the hangar.
