Installed the ELT mount today. After initial fit I decided to modify the mount to give more space for the rudder cable running behind it. I fabricated two extensions 1.250" wide by 7" long out of 0.040" scrap material. In image two you can just make out the cleco behind the J channel. Normally the five clecos in front of the J channel would be behind it. In image three you can see one of the extensions hanging above the ELT mount.
