I installed the fumes disposal tube and set the oil cooler butterfly valve in place. I will locate where the cable control comes through the firewall after I start to work on the panel. I also set the 4" oil cooler SCAT tube in place. The 2" heat SCAT tubes were set in place so I can start to identify places where other equipment may be installed. Finally, I added the lower spark plug wire clips so that I can get an idea of where the exhaust cylinder probes could be installed.
