Make the angle bracket for the music input to the GNS340. Drill the holes for the platenuts and the plug adapter. The platenuts holes were drilled after the holes were drilled in the avionics frame. This way I was able to position the bracket so it is flush with the front of the metal plate holding the instruments. Install the platenuts and paint the bracket. Install the music angle as per picture (Avionics229).
