SUCCESS (for now, anyway).
Our area does have an 'old fashioned' hardware store. While they had a place for a 8mmx1 set of bolts, that area was empty. OTOH, I was able to buy a 3 foot steel breaker bar that would fit over the 1 1/8" end of my wrench, and got that for $4.50.
And Home Depot (a 40 mile drive away) surprisingly had some 8mmx1 bolts so I bought one of the proper length. Given those two items (8mm bolt holding the extractor tool in place plus a 3' steel breaker bar) I was able to break loose the BB on the drive side. Surprisingly it stayed SUPER TIGHT until it was more than halfway out. I had to use the breaker bar for at least half of the extraction.
And once the entire BB assembly was out the non-drive side cup was only marginally easier to remove. Actually, since I could not hold the tool in place (I didn't have a washer big enough to use to clamp the tool in place), that piece actually took more time/effort than the drive side piece.
But the damned things are now outta there. I'm done for the evening and re-assembly starts tomorrow. I assume that this will be equally frustrating.
