I am behind on my c.r. so I hope my response has not been covered already, but Mark, if I recall, isn't the backside of that adapter peened in a couple of spots to keep it from easily unthreading from the bolt? This would explain why it feels almost impossible to remove. I believe you can back that bolt out without damaging the threads. It's been quite awhile since I have fiddled with a derailleur and adapter, so take my words with the proverbial grain of salt.
My other question is, why would you even want to use that anchor of a derailleur? No offense intended, just curious. In my experience they have never worked that well.

Steven Willis also mentioned that. I was hoping that the one here was sleeved too, but alas, it is just a simple back nut, six-sided and flat on front and back. In addition ... MAN! ... I'm a fair bike mechanic, but that pivot bolt just didn't want to thread out of the black adaptor ... it felt like it was tightening the internal spring while trying to loosen. The threads are clearly standard right.
After fighting to less than an eighth of a turn, I paused and thought. Is there any reason not to simply mount the unit & adaptor, rearward of the integral hanger, and pretend the latter isn't there? Seems to me it will lengthen the chainline, and I think I can afford the weight penalty. :)
Here are a few shots of this tried on, although the back nut is not yet
replaced for actual use:

So whadd'ya guys think ... will this work ok? I realize it gives me just a bit more funk edge on Harvey, but let's be realistic ... can anybody really, ever, out-funk the original FunkMeister Harvey? Really now? :)
Hope this solves it. Thanks for everyone's help!
