Tried to start wrenching off the two drc valves tonight with the nice new ones dave sent me, and i can't get this bolt loose (labeled 1) because the quick coupling (2) moves too much in its housing. Is there some way I am supposed to get the quick coupling not to move? I have tried tightening open ended wrenches on it, but the end piece where I have specifically labeled 2 turns a little bit.
