That is an interesting repair, it is very similar to what I have been doing for years except I remove the arm and put it in a vice to bend it. If you look at the arm, the aluminum part from the eye that mounts it to the place where it makes the 90 degree bend, place that part in the vice and squeeze it a little bit, this will achieve the same thing as performing CPR on it like in that thread. Myself though, I would try the CPR method first and if it has the desired effect then run that sucker but if you do not get enough of what you are looking for then take it off and use the vice. Put a rag in the vice first so you do not scratch it up.
