Does it have a pin/blade interconnect socket? I think the pin is used to carry the signal, not the blade.

Here is one that the magnet is way off center. No rubbing and sounds fine. I betcha it was that way since new.

I'd take them to the wire wheel, poke them through a piece of cardboard, dust a little black paint on the heads and call it a day.

Easy one for me. They played this as there encore in 2016 at the Fillmore in MD. Was a great show! https://youtu.be/yUi_S6YWjZw?feature=shared https://youtu.be/bPiQhOeXE_Y?feature=shared

That's a valid concern. I would carefully remove them from the cabinet before drilling for hurricane nuts, but definitely re-use them if they are in good shape.
