I had to put some reliefs in the instrument panel frame in the top right corner of the GTN 650 opening and the G3X 10 inch display. I knew that this would have to be done but of course waited till I cut the prototype panel in order to know how much I had to clear away. It took a little bit to do as I used the panel opening as a guide to mark it and then removed the panel and used the dremmel to cut the excess away.
I then started inserting some of the boxes. Got the two G3X boxes in and the GMC 507 autopilot control inserted.....everything fits great thus far!
