Well I decided to spend the money and get the EFIS displays upgraded to the larger high resolution displays. $1,200.00 for both. I should have them back in a week. So I removed the displays and boxed them up for return to Grand Rapids Inc. Then I cutout the 1/2" of panel below the EFIS cutout to make room for the new displays. I'll wait to drill up the bolt holes once the displays arrive. I also trimmed the map box doors 1/2 and inch as well.
