Here is the ADAHRS bracket riveted in place. I used flush 3/32 rivets. I put the lip on the front with three bushings for the Pitot, Static, and AOA tubes to run thru and then they'll attach to the ADAHRS. I was able to get the dimensioned drawings off the Dynon website. These bushings will hold the tubes and keep stress off of the fittings so to minimize chance of leak from vibrations. I remeasured and it is flat in all directions with the longerons.
