Brief Description: Attach accessories to the firewall
I started installing the accessories and mounting brackets to the firewall. I decided to try to mount as much of the stuff as seems reasonable prior to putting the firewall back onto the fuselage.
I've included a photo of the heater line opening in the firewall taken from the cockpit side. This shows the fabric covering. The small photo does not look good, but if you expand it you can get some idea of what the fabric actually looks like.
