Lots of miscellaneous work today. Installed a central grounding bus on the back of the firewall, this required drilling new mounting holes and moving the battery ground strap to the new attach point. The old nutplate location was just filled with the AN4 bolt and left. Assembled most of the oil cooler with line fittings and then assembly of the mount. Almost finished this assembly, ran oout of clear silicone to glue down some P seals. Installed one piece of baffling to see how much work this will be. Looks like the baffles will not be very difficult to finish up.
