I get you would cut off the molex connector. Did you keep in the socket wrench in the middle or temporally used it to push it out to the walls of the tank (removing the socket wrench before putting the cover plate). In the B31 thread, it seemed like he kept the brass slug he milled in. I also assume you put mica in between the tank wall and heater, to protect from the heater shorting electrically to the tank? Or is that not needed at all?
My B31 is missing the cover plate but actually had the heater (sandwiched between lots of mica) then an iron band that pushed it to the walls. Nothing in the middle other than a big hole - say like a donut. So I don't know if Empire had originally an iron/brass core in that center void / hole.
Sorry if I am being stupid, though I am ignorant how it was originally from the factory
