I've removed the bar completely and I've got it in a bolted-down vice. I've disassembled the shifter to expose the inner bolt, but I can not turn that bolt, even leaning into it. I'm a little concerned about stripping the bolt head (rounding it with the hex wrench), but I'm also wondering if I'm doing something wrong. I've tried both directions just in case it's reverse threaded for some odd reason. I've also soaked the shifter it in liquid wrench also, as well as I could.
Like I said - help!
Try a couple different hex wrenches in it and find the one that's tightest. Then, turn it
clockwise (like Auntie Team said) with as much force as you can muster.
There's a fair amount of aluminum-on-aluminum contact in there. If they weren't properly lubricated in the first place, things may have corroded together. You may have to cut the bars apart to salvage the shifter.
If you destroy the mount inside the handlebar, I
think you can replace them with the Silver bar-end mounts from Rivendell:
