Ah, thanks! I do have that new type of anti-rotation bracket, and it did seem to me that the safety wire on top of that was overkill... good to know I was right.
Another thing that occurred to me is that with that anti-rotation bracket, it will be impossible to remove the pickup tube for service without drilling the rivets out and removing the bracket. Is this correct? Also, is it a pain to rivet that bracket on with the nut already in place? This is the only way I can see to do it.
Thanks again.
