Today, I mounted the Skyview Engine Monitor Module and the ARINC-429 Module to the left side of the interior. I used the same general technique that I used on the right side to mount the ignition systems. I used 3/4" x 3/4" x .060 aluminum angle to mount the modules to. I attached the angles front and back to the firewall and second bulkhead respectively. I used 2 angles for each attachment to further strengthen the attachments. I also used .060 plates between the angles to mount the modules to. Nutplates are mounted to these plates to secure the attachment bolts.
