Thanks for the tips. I've purchased both a dead rear and a spare pinch from two CR members as a first step. If neither work, then second step is to drill out stainless M4 bolt. Yellow Jersey had an extra, but that's a last resort (would cost more than the der is worth).
I do have extra Dia-Compe pinch bolts, but I'll reserve those parts for now as I still have use for them.
In the future I must learn to not over tighten. My original thought was to tighten for added security as shifting was a little difficult. Of course the difficulty was not the fault of the derailleur. I had routed my cables from Suntour bar ends through the tape for a clean look and the old coil cables weren't having it. I've since replaced with new lined cables and it works like a dream (with an XC LTD as the replacement).
