First was rear heater deletion. Got rid of the long metal tubes and then the heater box assy itself. The deletion leaves 4 holes in the floor. Luckily they are 25mm in width so I ordered the correct plugs to fill the holes from the top and the bottom. 90950-01011 They should be here next week.
Maybe keep the parts just in case you have some kids someday. They will appreciate warm toes on cold days and snow runs.
