Nice progress! I have been thinking about mounting my evaporator to the firewall too once I can afford to get it. Since I'm hoping to keep my firewall clean and not have bolts coming through it, I was doing research for options a while back. I believe that full custom fab has a bracket that mounts to the floor below the pinch weld and thus there is no need for drilling through the firewall. I found this info somewhere on this forum but I can't remember where specifically.
