Just a quick update.  Today I went back to my required items list for my engine and decided to finally pull the trigger on the Lord Engine Mounts/Vibration Isolators.   These are used in-between the actual motor attach points and the Dynafocal engine mount.  This specific model #J7402-24 is called out for Long-EZs and Cozy’s since it provides better vibration isolation at engine start-up and power down.
