You could also just re-do the one you have, if you have access to a press, you'll have to heat it, I use a propane torch, just put something like a small piece of aluminum between the press arbor, and the arm, so it won't skin it up, and warm it up, I usually start pressing when either end gets good and warm to the touch, then go slowly, and straighten both bends a little at a time, til it aligns closer to the middle, I'd say if you mark the arbor, and move down about a half inch on each bend, you'll be awfully close, just remember, it doesn't have to be red hot to bend, had a guy do that one time, and this guy had an engineering degree!
