I decided to go to Plan B. I didn't know there was a Plan B until we inserted the glove compartment avionics assembly into the glove box and I discovered the Comm radio just didn't fit to my liking. It extended above the top edge of the glove box opening which wouldn't let me remove it. The work involved to lower it was just not worth it. I removed the assembly from the aircraft, then removed the radio and reinstalled it in place of the ADS-B box on the shelf in front of the glove box. I'll find a place for the ADS-B later. With that done, we reinstalled the assembly into the glove box and riveted it in place.
