Just got an upgrade of Avionics and no longer need these parts.
They all work great and no issues with anything. Actively just flew with them a few weeks ago, right before the upgrade. These were all removed by a professional Avionics shop, have been stored properly afterwards and cared for during use otherwise. Came out of a Cessna 172.
