I didn't go through the trouble of grinding a wrench down, but I watched the nut to make sure it didn't turn with the lock nut. (By the way, the $25 wrench was made in Taiwan.. may be the same wrench they use on Rocket IIIs there.. lol) I packed the top bearing with synthetic grease I had in the shop, like a normal wheel bearing, and did end up using a needle greaser on the bottom bearing as I didn't want to unhook everything.
It's all back together this evening, so I'll check it out on the way to work tomorrow..
OH.. and now my dang ignition switch is loose! and the screws that hold it in are like reverse torx heads. I was going to snug them up with a small six point socket, but they are smaller than my smallest 4mm.. lol Oh well.. hopefully it will stay in place a little while longer.
