I'm climbing in off the ledge.
I was able to remove the electrode tip.
Setting a 150w halogen work light in next to the head and lifting up the thick weathersthrip seal that's on the inner fender, I was able to get a better look into the hole. I could see a shoulder of the electrode sticking back. The magnetic tricks still didn't work. But the idea to use something sticky did (HUGE thanks to "turbobenz"). I wadded up some 3M strip caulk (dumb-dumb) onto the end of my long drill bit and simply dragged the electrode right out. It was as if I knew what I was doing

.
But I'm not out of the woods yet. The threads in the head or so wallowed out, that even though I've recut them, they are too large a diameter to hold the GP tight. NAPA can get a heli-coil kit by Tuesday for $68, so I'll have to wait until then.
You guys have no idea....actually, what am I saying, of course you do....how much you've helped me. Thanks a million times over.
