Electro Voice 667a (668) disassembly?

[OneRoomStudio]

I picked up an EV 667a for a good price, but it needs a little restoration. Anyone know how to get into these? I know how to access the switch-pins at the rear of the mic, and I know how to remove the grill (same as every other EV mic), but I can't figure out how to get into the body.

There's some info here: https://www.coutant.org/667a/index.html
and here's the engineering data sheet: https://products.electrovoice.com/binary/667A Engineering Data Sheet.pdf

Anyone have any other info?

Well, I figured out how to get to the diaphragm. Unfortunately, I also found that one of the magnet wires to the center coil was hanging on by a thread, and it broke just as I pulled the protective mesh screen off. I'm guessing I'm SOL now. Does anyone have any magic ideas for repairing it at this point? @panman maybe?

Well, proper pics from the situation might help to assess, what can be done.

Thank you! It's a bit difficult to see, but if you look closely, you'll notice that one of the green coil wires has become disconnected from the coil. It broke right at the surface of the diaphragm, so there isn't enough wire left to solder to.
