The continuing saga of aircraft systems. A long time ago when I built the firewall I installed the appropriate brake line mount for a nose gear aircraft. Now that I am building a tail wheel version I needed to change that mount. In image one you can seen the old mount in the lower left of the firewall. I drilled that out and removed it. Then after fabricating the mount you seen in image three I riveted it in place of the old one. All of that took longer than I anticipated.
