Like the old comedian Dave Gardner once said. "After looking at it, sitting back and studying it a little bit, I made the con--clusion>>>>>" Could not you just machine a flat spot on the other side of the stop or arm so you could start the clamp bolt easely from the other side and put in in backwards to act against that coin to make it a spreader bolt?
I guess you might say IOW is like GE "better ideas through BS".
