I picked up the backup battery tray and bracket from powder coat today. It took a while to get it installed but I got it done. Ready for Chris to get it hooked up tomorrow.
I also picked up the radiator mount and got it installed.
The bypass valve and tee for the coolant/heater system arrived. I'll need a few more clamps to complete the installation but the hoses are cut and fitted.
I spent the rest of the day swapping out temporary nuts for permanent lock nuts I had installed in the avionics bay on various trays.
